A: There are many classification methods for the structure types of rolling bearings. Among them, according to the load direction or nominal contact angle that they can withstand, they can be divided into radial bearings and thrust bearings.
◆ Radial bearing
Radial bearings are mainly used for rolling bearings that bear radial loads, with a nominal contact angle from 0 ° to 45 °. According to the different contact angles, they are divided into:
● Radial contact bearings: radial bearings with a nominal contact angle of 0 °;
