Whether you are a highly skilled and qualified engineer or workshop technician, this comprehensive resource will provide you with the necessary understanding to improve the reliability and efficiency of your machinery. We invite you to explore the critical issues of bearing lubrication with us because you want your systems to work trouble and problem-free for a long time.
What Are Angular Contact Ball Bearings and How Do They Work?
Understanding Angular Contact Ball Bearing Design
Angular contact ball bearings are designed to carry radial and axial loads simultaneously, making them appropriate for components rotating at high speeds and with great precision. Using this type of bearing makes it possible to keep in touch with the balls at an angle concerning the vertically oriented raceway. This is possible because this design’s inner and outer raceways are not in the same line.
Contact Angle: This is the angle between the imaginary line joining the point contact of the ball and the raceway, which moves the ball along the lines perpendicular to the racetrack. Standard contact angles are 15° with some degrees, 25° with some degrees, and 40° with some degrees. Increasing the contact angle at the site of loading the bearing leads to the inclusion of additional load direction but will affect the radial load capacity.
Load Ratings: Angular contact ball bearings are dynamic and static load-rated. For these parameters, these products determine maximal endurance stresses to be sustained by a particular rotating part while delivering expectancy service duration. The manufacturer’s specification should be referred to when using the bearings in specific applications that require working bearing load ratings.
Bearing Size: The inner diameter (ID), outer diameter (OD), width, and other bearing dimensions must be considered, dampening how they fit within the machinery. This varies widely depending on the use; dimensions remain options from small (10 mm ID) to large (100 mm ID).
Speed Parameters Rating Limitations: Every bearing has a relative speed beyond which performance degradation or bearing damage may be expected. Thermal overloads of this nature may result in overheating, leading to bearing burnout.
Materials: Steel AISI 52100 angular contact ball bearings are the most common material for high-precision angular contact bearings, where weight and strength are optimal. Advanced applications may use ceramics or composite materials to save weight and enhance wear resistance.
Networking these parameters is vital, especially in selecting the most appropriate angular contact ball bearing for a given application to achieve the intended objective at optimum completeness.
Common Applications of Angular Contact Bearings
More often than not, angular contact bearings can support axial and radial forces, making them suitable for orientation in various industries. For instance:
Machine Tool Spindles: In this line of action, angular contact bearings are high-speed and precise. The speed rating is critical, and spindle bearings should be able to take high-speed RPM without bulking. For instance, this is the case when manufacturers suggest having specific load ratings because the axial load is very high immediately, and such recommendations are usually followed to maintain stability in use.
Automotive Gearboxes: Angular contact bearings are used here as they are efficient for gear alignment. In this case, one can be proud that the kinematic parameters and characteristics are sustained throughout the cycle. As for materials, standard applications use high-quality steel, whereas advanced gearboxes require developed materials.
Pumps and Compressors: These bearings are also used in rotating machines with axial loads. Conveniently, the size of the bearing and the speed ratings are critical; they have to be suitable for the set assembly and work in a region where the speed can not cause breakdown.
Conclusively, there is no doubt that all the factors affecting the machine’s performance, especially the angular contact bearings, are most often the design requirements and are bound to be very important when evaluating their specific applications for high implementation under precision load and speed during operation. Therefore, it is essential to comprehend load ratings, bearing size, and speed ratings for that purpose.
Benefits of Using Single Row Angular Contact Ball Bearings
Due to the nature of their design, single-row angular contact ball bearings have several unique features that stand out in high-performance tasks. The most important of these is the fact that both axial and radial loads may be supported, thus broadening the possibility of machine configurations. For example, during my studies of the most authoritative industry sources, I discovered that these bearings are designed not to stretch even when working under cumbersome loads, enhancing machine alignment.
In this respect, the following parameters are indispensably of great importance:
Load Ratings: In the case of single-row angular contact ball bearings, hypertrophic or single-bearing axial load capacity in Newton (N) Units, axial load rating (ALR)- also specific radial load rating, which broadly details the features of their utilization. The higher the load rating number, the more the bearing does not fail under heavy operational loads.
Contact Angle: Standard contact angles (15°, 25°, or 40° are the most used) affect the bearing’s performance characteristics. The axial load capacities are believed to increase when the contact angle becomes wider than optimum.
Speed Ratings: This measures optimum rotational motion, often expressed in RPM revolutions. Single-row angular bearings can operate at speeds greater than 30,000 RPM and exhibit components suitable for spindle systems and other high-velocity arrangements.
Material Composition: Some high-grade materials demand high performance in high-temperature environments, while some can withstand relatively varying temperatures but offer low performance. High-grade materials used in bearings ensure that the load-carrying devices retain the geometry in hostile conditions.
In essence, I can be assured that my applications will be performance—and reliability-oriented due to the advantages the single-row angular contact ball bearings provide regarding load capacity, contact angles, speed ratings, and material selection.
Why is Lubrication Critical for Angular Contact Ball Bearings?
Importance of Bearing Lubrication
Lubrication is fundamental to the functionality and lifespan of angular contact ball bearings. It assists in reducing the friction between the moving surfaces, thus preventing overheating or excessive wearing away. From my review of the top three websites, I have noted several key metrics that stress the need to lubricate properly:
Viscosity: This characteristic allows one to determine the lubricant capacity to cover the surfaces of the rolling elements in a film-like manner. I observe that having optimal viscosity provides even lubricant distribution and low frictional or wear contact area.
Temperature Range: The bearing’s operating temperature range must be known. The lubricants should then be based on this range to avoid degrading over time and compromising the system.
Lubrication Frequency: Relatively low maintenance re-lubrication intervals are standard for mass dampers used in this manner. The websites caution against insufficient lubrication, as it leads to increased wear and, ultimately, failure of the bearings, especially in high-speed cases.
By recognizing these parameters, I am confident that I can appreciate and justify the importance of adequate lubrication in enhancing the reliability and performance of single-row angular contact ball bearings in my applications.
Effects of Improper Lubrication on Bearing Service Life
Insufficient lubrication adversely affects the duration of angular contact ball bearings and, as a result, most of the time leads to some sort of untoward results. Research across the top three websites provided enough information that the use of the following technical parameters makes clear the negative impact of insufficient lubrication:
Friction: If insufficient lubrication exists, friction experienced during surface movements is hard to avoid, leading to excessive heat fires. Raised temperatures can harm some bearing parts or even lubricant characteristics, which may result in a fatal failure.
Accumulation of Capital Quotes: Lack of adequate lubrication means that wear debris cannot be washed away, which may build up and further introduce more wear to the bearing surfaces. This unique environment hastens the wear and reduces the bearing’s service life.
Crusher: The bearing surfaces are moist and contaminated due to the absence of appropriate lubrication; hence, corrosion occurs. Pitting and spalling of the corroded surfaces make the bearing less functional and reliable.
Lubricant Degradation: In the case of inappropriate selection of a lubricant, it may work best under optimum conditions and may dissolve earlier than expected. Therefore, the protective film’s structure is affected, causing wear and heat to worsen.
Fatigue Failure: With time, failure under fatigue slowly develops due to increased stress from insufficient lubrication. The material eventually undergoes cracking after many load cycles. This generally leads to total expense depreciation of the bearing or to performance loss of its applications.
These parameters make one appreciate the need for proper and consistent lubrication to avoid bearing failure and enhance bearing life.
How Lubrication Enhances Load-Carrying Capacity
The application of suitable lubricant increases the load-carrying ability of the bearings mainly because of the reduction of friction and wear in dynamic contact surfaces. Here are the factors in which lubrication is essential:
Formation of a Protective Film: Excellent lubricants create a constant film between bearing surfaces, eliminating metal-to-metal contact. The stain film formed in the bearing facilitates rotation at lesser friction inertia and, therefore, helps better load application without overheating, which means heat bearing out.
Heat Dissipation: Moving parts generally develop wear and heat during motion, which suppresses the eccentricity of the bearing upon the lubricant. Cooling down the operating—-shipping—temperature means a longer service life of the lubricant and the bearing materials, which withhold thermal decomposition.
Reduction of Wear: The bearing is comprehensively lubricated, so minimal metal-to-metal contact occurs, and wear is registered at low levels. Due to the pumping out of wear debris and other contaminants from lubricants, cleaner, unsoiled surfaces can be loaded for extended periods.
Improved Load Distribution: The load exerted on the bearing surfaces is uniformly spread out as lubrication occurs, lowering the chances of developing concentrated stresses. This eagerness to ensure even weight load distribution is vital in expanding bearing life by preventing premature fatigue under heavy working loads.
Technical Parameters: Several factors that influence the performance of lubricants have been identified; these include viscosity, endurance in high temperatures and other environmental conditions, and wear additives. The lubricant must have a proper operational viscosity; high-viscosity lubricants might need to be used for high-temperature applications or under heavier loads. Temperature stability guarantees that the lubricant maintains its features over diverse operating activities. Load-carrying additives, EP additives, in this case, help to improve wear protection under high load conditions.
On a final note, the selection and follow-up of the lubricants are essential every time, significantly when enhancing the load-carrying capacity and reliability of bearing units.
What Types of Lubricants Are Suitable for Angular Contact Ball Bearings?
Choosing Between Grease and Oil Lubrication
When comparing grease and oil for angular contact ball bearings, some factors must be considered depending on the specifics of the application. Below are the most important factors most people practice in this field, gathered from the best industry sources.
Temperature Range: Grease generally works properly in situations below 120 °C (248 °F), while oil can work at higher temperatures and is thus more appropriate for harsh environmental conditions. The lubricant’s viscosity index must also be considered when selecting it because it determines the overhanging mass at varying temperature conditions.
Speed of Operation: Oil lubes are recommended for applications with high speeds, as oil has less viscosity, resulting in less heat being generated. Vice versa, grease can be used ably for low-speed applications.
Contamination Resistance: Grease allows minimum pollution and penetration and is, therefore, most applicable in cases where dust or other foreign elements might be present and cause pollution. Oil is good in thermal mass removal but has the disadvantage of leakage, hence mass loss.
Application Method: Grease is an improvement in its application and maintenance complexity, which does not require a unique lubrication system, while oil – application will partly depend on pumps and seals. Oil systems are comparatively less complicated for lightweight automated systems since plenty of lubricants exist.
Load Capacity: Greases and oils have additional load–carrying capacity, and several additives help them perform well in varied loading situations. Extreme pressure (EP) additives in grease can help in high-load applications, while oil often contains anti-wear additives to protect components under shock loading.
In conclusion, apart from these practical conveniences, the decision to use grease or oil lubrication also depends on parameters such as temperature/frequency chiefs, speed of parts effectiveness, level of contamination, maintenance efforts, or load criteria, among others. Understanding these technical parameters is critical to ensuring the proper functioning and durability of angular contact ball bearings.
Critical Properties of Bearing Lubricants
A careful assessment of the properties helps to conclude the selection of bearing lubricants, which efficiently enhance the performance of the bearing system. Based on the conclusions drawn from the top three websites, I have ascertained the following essential technical parameters that justify the choice of lubricant.
Viscosity: It is well known that a lubricant’s viscosity rating dramatically influences its ability to minimize friction and wear coefficients. Higher-viscosity grease proves efficient in high-load conditions, while low-viscosity oils are most efficient in high-speed applications for lubricating moving bodies.
Temperature Stability: I discovered that a lubricant’s ability to preserve its characteristics within a range of temperatures is significant. Greases usually perform better at higher temperatures, while oils perform better in environments with varying thermal constants due to low thermal expansion.
Additive Technology: Next, it is necessary to devote special attention to anti-wear agents and extreme pressure (EP) additives. I’ve noticed that EP additives are extensively used in greases, significantly increasing their load-bearing capacity. At the same time, ions contain anti-oxidant and anti-corrosion additives used on components while in storage.
There are ways to maintain the performance level of angular contact ball-bearing systems based on applying well-selected lubricants.
Optimal Grease Lubrication Conditions
The activities that need to be performed to guarantee proper greasing of the bearing with the grease are geared towards some conditions influenced by the previously highlighted technical parameters. Here are the main lubrication criteria as well as the rationale for selection based on the analysis of the top three websites:
To hand in the work within a set time frame, including workmanship, cost, OS, and other ‘the beauty of the system lies in its design’ predictions. Grease performs well in situations that are not likely to be significantly contaminated. In critical applications, optimum grease with a high viscosity index should be used to ensure sufficient performance when applying different load and temperature conditions.
To handle load conditions: Greases with superior additive technology would be appropriate for high-load-requiring applications. Adding EP additives improves the grease’s ability to sustain heavy operating conditions, lowering the wear and tear on bearing surfaces.
Temperature Conditions: Thermally stable Greases should be used in applications where high operating temperatures prevail. Select a grease that works properly in the anticipated temperature range and will not break down too quickly to be serviceable.
Relubrication Intervals: It is essential to consider and adequately set relubrication regimes. They are determined by the shear sensitivity of the grease and the stress applied. Since relubrication intervals are prolonged, the lubricant risks deteriorating, and there will be greater wear.
Following these optimum conditions and exemplifying them with the technical parameters of viscosity, temperature stability, and additive technology for angular contact ball bearings can substantially improve their performance and service life.
How to Properly Apply Lubricant to Angular Contact Ball Bearings?
Methods for Lubricating Bearings
Sometimes, I have to rely on a few lubrication techniques for angular contact ball bearings, supported by information from some of the industry’s leading websites.
Grease Packing: In situations that require constant lubricant addition, I find that the bearing is most effective when packed with grease. The grease should have a high viscosity index of about 100 to 150, making it performance-oriented when subjected to changing temperatures and loads.
Grease Injection: I usually use a grease injector in dynamic applications where accurate and correct lubrication is critical. This makes it possible for me to pump the right volume of aggrex grease into the bearing, which comes in very handy when working in areas with varying temperatures, making using EP additives for load bearing very useful.
Oil Bath Lubrication: In most cases, when the machine is likely to operate continuously, I prefer using the oil bath method. In this method, the
the whole bearing is immersed in oil, which, in everyday situations, has a viscosity of about ISO 32 to ISO 68, enabling proper lubrication and cooling.
Manual lubrication: For instance, before such a task, to avoid any possible contamination of the grease or grease deterioration, I strictly follow the renominated intervals for methods of relubrication, which is once every six months or based on operating circumstances.
However, considering these measures, tailored to the application’s particular load and temperature regime, it will be possible to considerably improve the performance and life of angular contact ball bearings.
Steps for Grease Lubrication
Determine the Right Grease Type: Bearing grease must be chosen based on the bearing application and operating conditions. A lithium or polyurea, NLGI grade 2 or 3 grease should be used, as it offers good stability and lubrication under various working conditions. Justification: A change in operating conditions and loads influences the type of grease required, which is critical for the bearing’s efficiency.
Clean the Bearing: Before new grease is applied, the old grease and contamination must be cleaned off the surfaces upon which the new grease will be applied. Use a mild degreaser that does not compromise the bearing substance. Justification: If the old greases are left or residual, they will degrade when new lubricant is applied, affecting the lubricating effectiveness.
Apply the Grease: A grease gun or injector is the best method. The angular contact ball bearings cavity should be filled to 30-50% of its volume. This gives enough lubrication while avoiding increasing the volume of grease, which may cause high pressure and, hence, leakages. Justification: Raising the lubrication to a point higher than required can cause overheating and failure of the bearings before their time.
Recheck After Installation: After the initial lubrication has been done and the bore of the bearing mounted, run for average temperatures/conditions with the bore of the bearing and check if any unpleasant sounds would have been avoided or if no unpleasant characteristics in any size rise in temperature from the normal operating levels of the lubricated bearings. If the lubrication needs to be adjusted, this may be done. Justification: This is beneficial in discovering potential problems as early as possible for optimal functioning.
Establish Relubrication Program: Create a relubrication program for inhaler devices, which shall be scheduled periodically depending on either manufacturers’ instructions or operating history data. This usually occurs every six months or when some wear is noticed. Justification: As noted before, periodic interventions are necessary to avoid progressive grease wear and smooth out the changes in lubrication amount over time.
On the practical side, it is worth noting that, following these steps and taking into account the appropriate technical parameters, it is possible to achieve efficient grease lubrication of angular contact ball bearings, which will, in turn, significantly affect their performance and service life.
Oil Lubrication Techniques
Reflecting on the use of oil lubrication for angular contact ball bearings, one of the above resources, I outline many essential techniques and considerations in the best practices:
Appropriate Selection of Oil: It is paramount to choose an oil that aligns with the manufacturer’s recommended viscosity and temperatures. Some sources recommend oils that give rise to decent film strengths to support the surfaces under increased loads. Justification: Using the wrong oil may cause inadequate lubrication, increasing the wear rate and resulting in premature failure.
Sufficient Quantity of Oil: It is also essential to put the oil at the right level. The oil should be filled at a level that ensures optimum bearing lubrication and does not cause excessive disturbance to the housing. Justification: An improper oil level can either result in cavitation when there is not enough oil or excessive lubrication when there is too much oil, both undesirable effects for the bearings.
Surveillance of the Health of Oil: Asses the encrustation of the oil and the deterioration of viscosity regularly. Implementing an oil analysis program can assist in knowing when the oil should be changed. Justification: When oil breaks down due to wear, lubrication available to the parts is reduced, leading to more wear and problems in running forms.
Implementing Oil-Recirculating Systems: An oil-recirculating system guarantees constant lubrication and cooling in cases of speed or load fluctuations. Justification: This system stops overheating and ensures that all bearing surfaces receive oil dispersed quickly.
Therefore, I can ensure that the lined lubrication techniques with oil for the angular contact ball bearings meet the technical requirements, extend the service life, and improve the bearings’ performance.
How to Maintain and Monitor Lubrication in Angular Contact Ball Bearings?
Regular Inspection and Maintenance Tips
To achieve this ambition, I concentrate on trying to accomplish the following strategies for proper lubrication and its inspection in angular contact ball bearings:
Scheduled Inspections: Inspection of the bearing systems and neighboring parts is already incorporated into calendar recommendations. This allows me to detect the initial stages of wear, imbalance, or overheating of the surrounding substance. Justification: This early response can address the problem of being surprised by failures and thereby improve the longevity of the bearing.
Vibration Analysis: Portable vibration monitoring systems can determine the operational status of any bearing. Elevated levels of vibration can be produced due to improper lubrication or misalignments. Justification: By using vibration analysis regularly, I avoid increased mechanical failure.
Lubrication Interval Checks: I make sure that lubrication intervals are not too high and are not exceeded due to operational conditions or manufacturers’ recommendations. Thus, bearing operating temperature and load conditions, for example, should influence how the lubrication cycle is determined. Justification: As recommended, interval time can avoid the high chance of lubricating failure to the bearing and performance draining out.
Documentation of Findings: I operate and maintain a comprehensive website of all the actions undertaken concerning the sealed bearing, more specifically, all inspected and analyzed, whether oil analysis and fixing of motion abnormalities have been done. Justification: Complete documentation helps in making sound decisions and helping to baseline maintenance trends for any given period, thereby improving reliability in general.
While observing the technical parameters, if I adhere to these inspection and maintenance tips, I can guarantee the effective operation and life of angular contact ball bearings for various applications.
Identifying Signs of Lubrication Failure
Angular contact ball bearings can sustain operation without consequences if lubricating failure is detected as soon as changes are noted. Several indicators distinguish the best-known leaders in such issues.
High operating temperature: High-temperature release is a clear indicator of insufficient lubricant on the surface. This could make bearing surfaces susceptible to too much movement and possibly even bearing damage. Justification: The surfaces of the bearings have to operate at a specific range of temperatures for their structure and working ability to be sustained.
Strange sounds: Together with the sound operation, noise can be heard when there is a grinding, squeaky, or rumbling noise, even when the parts are in motion. Justification: Proper lubrication makes it possible to avoid contact between metal surfaces in friction, resulting in less wear and noise.
Vibration Analysis: The patterns or the amount of vibrations are likely to change. This may indicate that some grease may be low or contamination may be a problem. Justification: A constant vibration measurement is an active protection against mechanical breakdown as it helps identify the early stages of failure.
Loss of Grease for lubrication or Grease Contamination: Grease loss in improper locations or the intrusion of contaminants like dirt or water reduces lubricating capability. Justification: Effective lubricants contaminated by foreign materials or leaking out are not usually effective. The Wynman System ‘R’ grease must not be allowed to wear excessively when operating, and for 3, it must be expected.
Sometimes, the lubricant used for bearings can also be inspected visually. The lint may be chronically red due to overheating or a burnt trace in the lubrication experiencing degradation. Justification: Routine inspections involving vision inspection frequently can further help determine the bad quality of lubricants before adversely affecting bearings even short of total replacement.
Angular contact ball bearing performance and life can be sustained through constant evaluation of the said indicators against set as operating values operating temperature, noise level and vibration amplitude.
Preventing Contamination in Lubricated Bearings
To avoid pollution within the lubricated bearings, I employ several methods I gathered from the best technical practices of applicable technical documents in the industry.
Sealing and Shielding: Bearings must be adequately maintained with appropriate seals or shields. High-quality seals help block the entry of dust and water into the bearings. Their correct placement and usage are warranted because they act as the first barrier to incursion.
Lubrication Selection: I use particular lubricants relevant to the application, considering the working temperature range and the bearings’ materials. For instance, selecting a grease that works efficiently between negative twenty centigrade and one hundred twenty centigrade can help enhance contamination barriers.
Regular Maintenance: It is advisable to develop a maintenance plan whereby the visual inspection and an actual mx around oil change are undertaken and done as scheduled. Nonetheless, routine checks should be done to detect possible leakages and contaminations of the lubricants, which underline the need for preventative measures to sustain the performance and efficacy of the bearings as required.
Environmental Controls: The emphasis on relative humidity and dust control is on keeping the working environment clean and dry. Since low dust and humidity levels harm bearings, I try to employ measures that prevent humidity and dust to increase the bearings’ lifetime.
Implementing such preventive measures not only upholds the integrity of the bearing but also maximizes its life of service, emphasizing the necessity of constant supervision and maintenance attention.
Frequently Asked Questions (FAQs)
Q: Why is proper lubrication so necessary in angular contact bearings?
A: Proper lubrication is essential in the case of angular contact bearings because it lessens friction, reduces wear on the inner surfaces of the bearing, and prevents the bearing from failing. It also ensures the machinery’s regular activity and increases the bearing’s service life so that no dirt enters it.
Q: In which way operating temperature interacts with lubricants in ball bearings?
A: Operating temperature also plays a vital role in ball-bearing lubrication. High operating temperatures cause the lubricant to undergo thermal degradation sooner than necessary, while low operating temperatures increase the lubricant’s viscosity, making it difficult for it to flow correctly. One must use a lubricant that is resilient to the operating conditions of your application.
Q: What are the recommended lubricants for the high-speed angular contact bearing?
A: Lubricants used for high-speed angular contact bearings must have low viscosity and be highly thermally stable. Greases that contain synthetic oils or lubricants engineered for high-speed applications are perfect for ensuring correct lubrication and restricting device overheating.
Q: How frequently should I lubricate my angular contact bearings?
A: It depends on operating conditions like speed, load, temperature, and environment. Typically, high-speed or high-temperature conditions will require more regular comfort levels. Please review the manufacturer’s instructions for more precise and thorough recommendations regarding the lubrication schedule.
Q: In which way is it better to lubricate angular contact bearings?
A: The best lubrication method for angular contact bearings is not universally applicable, as it depends on the type of application and the bearing design itself. Such systems usually include grease dispensing devices, oil dispensing systems, or specialized automatic lubricating units. In high-speed operations, oil mist or air-oil lubrication is preferred, and enough lubricant is applied to ensure lubrication quality.
Q: Will old grease affect the performance of angular contact bearings?
A: Yes, it will. Old grease negatively impacts the performance of angular contact bearings. Debris contamination is a major factor that will cause old grease to become ineffective over time. This is why it is essential to use fresh, good-quality lubricant and replace the old one regularly to help keep the bearings operating at their full potential.
Q: Why is the seal required in bearing lubrication of the bearing?
A: The seal in a bearing lubricates the internal mechanics and prevents contaminant inflow into the bearing.

Q: How would the bearing configuration affect the lubrication methods employed?
A: The arrangement of bearings impacts the effectiveness of load distribution and how lubricant flows inside the bearings. Bearings are appropriately arranged to help the lubricant cover all surfaces of the bearing system, which is very effective in controlling wear and fattening the lifespan of the bearing. If the arrangement is incorrect, lubrication may be insufficient thereafter, leading to damaged bearings sooner than anticipated.
Q: What are some of the effects of poorly lubricating angular contact bearings?
A: Lack of proper and adequate lubrication increases friction, which causes wear and tear and overheating, the adage promising eminent bearing dysfunction. It can also damage parts of the rolling element surfaces, paving the way for premature fatigue and extending the energy-free fatigue life of the bearing.
Q: Do deep groove ball bearings use different types of lubricants, considering the angle of contact bearings?
A: While deep groove ball bearings and angular contact bearings employ lubricants that meet high-quality requirements, the specific types may differ for each case. They are constantly subjected to axial and radial loads, often with very high speeds, which may require different types of lubricants than ones used in deep groove ball bearings.
