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:
Single-direction thrust ball bearings are composed of washer-like bearing rings with raceway grooves.
In double-direction thrust ball bearings, there are three rings with the middle one (center ring) being fixed to the shaft.
High rigidity thrust bearings designed specifically for ball screw support applications in machine tools.
These bearings provide excellent resistance to ingress of coolant and metal chippings, while providing highly rigidity.
