Understanding Angular Contact Ball Bearings Single Row
AMIGO’s Single Row Angular Contact Ball Bearings are high quality and have high-speed applications at top levels of precision. Both radial and axial load-carrying capabilities would enable these bearings to be employed even in severe conditions like automobiles, aerospace, and industrial equipment. One benefit of selecting AMIGO is that the single-row angular contact ball bearings can be superseded by those of other top brands like SKF, FAG, and NSK. The Company; AMIGO, manufactures bearings of the highest quality, which are fully interchangeable with the bearings manufactured by the best manufacturers in the industry.
Features and benefits
- High load restraints lifting capacity: The lower shoulder of the bearing is constructed so that numerous balls can be housed in it, leading to a rather high load-carrying capability.
- Excellent running capabilities: This design allows for quick increases and decreases in speed, which helps improve the device's running abilities.
- Easy mounting of fit-all bearings: These bearings can be fitted without adjusting the internal clearance/preload.
Temperature Limits
The permissible operating temperature for angular contact ball bearings can be limited by:
- Dimensional stability of the bearing rings and balls
- Cage
- Seals
- Lubricant
The bearings are heat stabilized up to at least 150 °C (300 °F).
Applications
- Automotive Industry: Used in car wheel hubs, transmissions, and steering systems to handle both radial and axial loads, ensuring smooth operation.
- Aerospace Industry: Integral in aircraft engine components and landing gear systems where high precision and durability are essential.
- Industrial Machinery: Employed in machine tool spindles, robotics, and automation systems to handle combined loads with high accuracy.

Single Row Angular Contact Ball Bearings Loads
Equivalent Bearing Loads
The Equivalent Dynamic Bearing Load is critical for evaluating the bearing's performance under dynamic conditions.The Equivalent Static Bearing Load is used to assess the bearing's ability to withstand static loads, particularly when the machine is stationary or moving at low speeds.
Minimum Load
To ensure optimal performance and prevent damage, cylindrical roller bearings must operate under a minimum load. The Minimum Load requirement varies depending on whether the bearings are single or arranged in pairs.
Â
Calculating The Axial Load For Bearings Mounted Singly Or Paired In Tandem
When a radial load is applied to a single row angular contact ball bearing, radial loads are also transmitted form one raceway to the other and it leads to internal axial load generation. When it comes to the adjustment of two single bearings and bearing pairs one behind the other, these points must be taken into consideration for the equivalent bear loads calculation.
Load Carrying Capacity Of Bearing Pairs
The values for basic load ratings and fatigue load limits listed in the product table apply to single bearings. For universally matchable bearings mounted immediately adjacent to each other, the following values apply:
- basic dynamic load rating for standard bearings in all arrangements and for AMIGO Explorer bearings in a back-to-back or face-to-face arrangement:
Cpair = 1.62 Csingle bearing - basic dynamic load rating for AMIGO Explorer bearings in a tandem arrangement:Cpair = 2 Csingle bearing
- basic static load rating:
C0 pair = 2 C0single bearing - fatigue load limit:
Pu pair = 2 Pu single bearing

Frequently Asked Question
Q: What are Single Row Full Complement Cylindrical Roller Bearings?
A: These roller-bearing cylindrical types have no cage and use all the available rollers for maximum radial load capability.
Q: What are the main benefits of Single Row, Full Complement Cylindrical Roller Bearings?
A: They have increased radial load carrying capacity, relatively swept volume, and higher robustness, even in construction, which allows them to cater to heavy-duty applications.
Q: In what industries do Full Complement Cylindrical Roller Bearings operate?
A: They are used in various industries, including heavy machinery, automotive, steel processing, mining, and wind energy.
Q: How are Single-row full-complement cylindrical Roller Bearings distinct from the ordinary cylindrical roller bearings?
A: This type of bearing is a little different from standard bearings in that it does not have a cage. This allows for more rollers in the bearing, hence increasing load capacity, although speed may be a problem.
Q: Is it possible for Single Row Full Complement Cylindrical Roller Bearings to support axial loads?
A: These bearings can be used mainly for radial loads but can support restricted axial loads also in some setups.
Q: What are the usual limits for the speed for Single Row Full Complement Cylindrical Roller Bearings?
A: Since there is no cage in the bearing structure, these bearings are geared towards low—to moderate-speed operation and are more commonly used in high-load systems.
Q: Are Single Row Full Complement Cylindrical Roller Bearings suitable for substituting other radial types of bearings?
A: Yes, they are often replaced with other similar bearing types from reputed manufacturers, provided they are of similar size and have the same load capacity.
Q: What is the effective maintenance of the Single Row Full Complement Cylindrical Roller Bearings?
A: Adequate lubrication and regular checks are necessary to comply with operational requirements and enhance bearing life although application of excessive loads may be detrimental.
Q: What considerations must be considered when choosing Single Row Full Complement Cylindrical Roller Bearings?
A: The load conditions, working speed, space limitations, lubrication method, and application’s operational conditions should be considered.
Q: What are the hazards of operating with a Single Row Full Complement Cylindrical Roller Bearings?
A: These include control of heat when high speeds are attained, proper lubrication, and shielding against dirt in inappropriate conditions.
