According to the type of thrust bearing structure
(1) Bearings are classified according to the different load directions or nominal contact angles they can withstand:
1) Radial Bearings - Mainly used for rolling bearings with radial loads, with a nominal contact angle from 0 to 45.
According to the different nominal contact angle, it is divided into: radial contact bearing ---- radial bearing with nominal contact angle of 0;
Concentric angular contact bearings - radial bearings with a nominal contact angle greater than 0 to 45.
2) Thrust bearings - Rolling bearings are mainly used for axial loads and have a nominal contact angle of more than 45 to 90.
According to different nominal contact angles, they are divided into: Axial contact bearings ---- Thrust bearings with a nominal contact angle of 90;
Axial angular contact bearings - thrust bearings with a nominal contact angle greater than 45 but less than 90.
