What Are Single Row Angular Contact Ball Bearings?

Single row angular contact ball bearings are specialized ball bearings that can support axial loads in only one direction. This design is made possible through a specific contact angle between the inner and outer raceways and the rolling elements. These bearings are not symmetrical, meaning they must be mounted in specific orientations or paired with another bearing when bidirectional axial loads are required.

Key Features

One-way axial load handling: Designed to support axial loads in one direction only.
High-speed performance: Optimized internal geometry for high rotational speeds and minimal heat generation.
Compact design: Space-saving structure ideal for compact mechanical assemblies.
High precision and rigidity: Suitable for demanding positioning applications such as spindles and motors.
Interchangeability: Fully interchangeable with global bearing brands, including SKF equivalents.

Typical Applications

These bearings are widely used across various industrial sectors that demand precision and reliability. Applications include:

Electric motors and pumps
CNC machine tool spindles
Gearboxes and transmissions
Compressors and fans
Automated machinery

Installation Tips

Ensure proper alignment to avoid uneven load distribution and early wear.
Pair with another angular contact bearing for dual-direction axial loads.
Use appropriate preload settings if high rigidity is required.
Choose correct lubrication (grease or oil) based on speed and temperature conditions.

Interchangeability with SKF

These bearings are often used as direct replacements for SKF models. Ensure to match the size, contact angle, and preload class when selecting an equivalent part number.

Conclusion

Single Row Angular Contact Ball Bearings offer an efficient and reliable solution for applications requiring unidirectional axial load support, high speed, and precision. Their design simplicity, combined with widespread compatibility with leading bearing brands, makes them a top choice for engineers and OEMs alike.
