Angle Rings For Cylindrical Roller Bearings

What Are Angle Rings for Cylindrical Roller Bearings?

Angle rings, typically identified by the series designation HJ, are ring-shaped components installed adjacent to cylindrical roller bearings, particularly NU and NJ types. While NU and NJ bearings are primarily designed for radial loads, they lack full axial location ability. Angle rings provide the necessary axial guidance when used in combination with these bearings.

Functions and Benefits

The main purposes of angle rings include:

• Axial Stabilization: Allow NU and NJ bearings to support axial loads in one or both directions, depending on the configuration.
• Enhanced Alignment: Help maintain precise alignment of the shaft and housing, reducing bearing wear and vibration.
• Improved Load Distribution: Support even load transfer across the bearing, increasing operational efficiency and service life.
• Extended Application Range: Make cylindrical roller bearings suitable for more complex loading and mounting conditions.

Design Compatibility

Angle rings are specifically matched with:

• NU Type Bearings: Which have no flanges on the inner ring, allowing axial displacement but requiring external axial positioning.
• NJ Type Bearings: Which can support axial load in one direction when paired with an HJ angle ring, transforming them into NJ+HJ assemblies with improved axial guidance.

Applications

Angle rings are widely used in industries where high radial loads must be paired with limited axial guidance, such as:

• Gearboxes and industrial reducers
• Rolling mills and heavy-duty transmissions
• Electric motors and pump assemblies
• Railroad applications and power generation equipment

Material and Precision

Manufactured from high-grade bearing steel, angle rings are hardened and precision-ground to ensure dimensional accuracy and optimal mating with associated bearing components.

Interchangeability

Corebearing’s Angle Rings For Cylindrical Roller Bearings are fully interchangeable with standard products from leading manufacturers such as SKF. This ensures seamless integration into existing designs or easy replacement during maintenance.

Conclusion

Angle rings are critical accessories for cylindrical roller bearings, enabling axial load accommodation and stabilizing performance in complex mechanical systems. When paired correctly with NU or NJ bearings, they significantly enhance the reliability and versatility of the bearing arrangement.
