Thrust bearings are designed primarily to support axial loads at contact angles between 30 and 90 degrees. just as with radial bearings, these bearings differ according to the type of rolling element they use: there are thrust ball bearings that use balls and thrust roller bearings that use rollers.
1. Single direction thrust ball bearings
The steel balls of single direction thrust ball bearings are arranged between a pair of shaft housing washers and the normal contact angle is 90 degrees.
2. Spherical roller thrust bearings
Just like the spherical roller bearings, the center of the spherical surface for spherical roller thrust bearings is the point where the raceway surface of the housing raceway washer meets the center axis of the bearing.
3. Cylindrical roller thrust bearings
Thrust bearings incorporating cylindrical rollers are available in single row, double row, triple row, and four row varieties. Cylindrical roller thrust bearings are able to receive axial loads only, and have high axial rigidity which makes them well suited for heavy axial loads.
4. Tapered roller thrust bearings
