Thrust Ball Bearings

Single direction thrust ball bearings with flat back face

Single-direction thrust ball bearings are designed exclusively to handle axial loads in one direction. These bearings include a flat housing washer and an aligning seat washer. Typically, the flat housing washer does not allow for angular misalignment. However, during installation, a gap of 0.5-1 mm can be left between the outer diameter of the housing washer and the mounting surface to compensate for minor angular errors.

Note:
  • Aligning seat washers must be ordered separately if required for specific applications.
Common Uses:
  • Used in compressors, centrifugal pumps, and other equipment where axial load handling in one direction is needed.

Thrust Ball Bearings

Double direction thrust ball bearings with flat back face

These bearings are designed to handle axial loads in both directions but cannot carry radial loads. Double-direction thrust ball bearings feature a flat housing washer and a self-aligning seat washer. As with single-direction versions, the housing washer typically does not allow for angular misalignment. A 0.5-1 mm gap between the housing washer and mounting surface can help accommodate slight angular errors.

Important:
  • Self-aligning seat washers must be custom-ordered for specific applications.
Typical Applications:
  • Suitable for machine tool spindles, gear assemblies, and high-precision machinery requiring stable axial support.

Thrust Ball Bearings

Angular contact trust ball bearings

Angular contact thrust ball bearings are designed primarily to carry axial loads, with the added ability to support some radial load. Compared to standard thrust ball bearings of similar size, angular contact variants offer a higher limiting speed and can be used for axial location in one direction. They feature contact angles of 45° and 60°, with smaller angles allowing for higher radial load capacity.

Benefits:
  • Supports both axial and radial loads.
  • Higher speed capability than traditional thrust ball bearings.
  • Provides enhanced radial load capacity, overcoming the limitations of flat-back thrust ball bearings.
