Thurst ball bearings

There are many types of thrust bearings that differ

according to shape of rolling element and application. Allowable rotational speed is generally low and special attention must be paid to lubrication.

Single direction thrust ball bearings have steel balls that are arranged between a pair of shaft housing washers (bearing shaft washer and housing shaft washer), and the normal contact angle is 90°. Axial loads can be supported in only one direction, radial loads cannot be accommodated, therefore these bearings are unsuitable for high speed operation.
