Thrust ball bearings with NSK's high-speed operation can be designed to withstand thrust load by rolling the ball rolling with a washer-like rings constitute Erdaogou. As for the saddle-shaped ring, therefore, thrust ball bearings are divided into flat seat type and seat type Aligning two types. In addition, such bearings can withstand axial load, but can not bear radial load. 
 NSK ball bearings, thrust-and two-way one-way two kinds. Thrust ball bearings One-way consists of two rings (shaft washer and housing ring), and a structure with keeping the ball into. Bi-directional thrust ball bearings from the three rings and maintain the structure of the two with the ball into. If two-way type, is taken from the cage with the ball caught the two axes in the form of circles.
