Thrust Ball Bearings
NSK Thrust Ball Bearings are composed of a "washer-like" bearing ring with raceway grooves for the balls and are classified into flat seats or aligning seats - depending on the shape of the outer ring seat. Designed to handle thrust loads while operating at high speeds, these ball bearings are able to sustain axial loads but not radial loads.
NSK's Thrust Ball Bearings are available in two designs: single direction and double direction. The single direction design comprises two rings, referred to as shaft and housing washers and a single ball and cage assembly. The double direction design, on the other hand, comprises three washers and two ball and cage assemblies. The ball and cage assemblies of the double direction type are separated by the shaft washer.
Product Features and Benefits:
- Available in two designs: single direction and double direction.
- To accommodate initial misalignments in an assembly both design are available with spherical aligning seats or aligning seat washers.
- High quality Steel - Ultra clean steel to extend bearing life by up to 80%.
- Advanced Grease Technology - NSK lubricants that can extend grease life and performance.
- High Grade Balls - Quiet and smooth operation even at high speed.
- Optional seating rings take initial misalignment.
NSK's range of Thrust Ball Bearings include: angular contact thrust ball bearing, single direction thrust ball bearings, double direction thrust ball bearings.

Single Direction Thrust Ball Bearings
Single-direction thrust ball bearings are composed of washer-like bearing rings with raceway grooves.
Double Direction Thrust Ball Bearings
In double-direction thrust ball bearings, there are three rings with the middle one (center ring) being fixed to the shaft.
Angular Contact Thrust Ball Bearings for Ball Screw Support
High rigidity thrust bearings designed specifically for ball screw support applications in machine tools.
For high load applications we have TAC-HR and SHR series
