Thrust Ball Bearings
Designed to handle thrust loads while operating at high speeds, NSK thrust ball bearings are composed of a "washer-like" bearing ring with raceway grooves for the balls. Thrust ball bearings are classified into those with flat seats or aligning seats depending on the shape of the outer ring seat. These ball bearings can sustain axial loads but no radial loads.
NSK's thrust ball bearings come 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
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.
