wheel bearing load bearing

 By Rolling structural type classification (1) can bear the load bearing their direction or nominal contact angle, divided into: a) radial bearings ----- mainly used to bear radial load bearing, nominal contact angle from 0 to 45. Press nominal contact angle is different, is deck crane bearing‍ divided into: radial contact bearings ----- nominal contact angle is zero radial bearings: Radial angular contact bearings ----- nominal contact angle greater than radial bearings 0-45 of . 2) thrust bearing ----- mainly used for axial load bearing, the nominal contact angle greater than 45-90. Press nominal contact angle is divided into different: Axial contact bearings ----- nominal contact angle of 90 thrust bearings: Axial angular contact bearing‍ angular contact bearings ----- nominal contact angle greater than 45 but less than 90 of the thrust bearing. (2) the type of rolling element bearing according divided into: 1) rolling the ball as the ball bearing -----: 2) rolling the roller bearings for the rollers -----. Thin section bearings‍ Roller Bearing press roller type, is divided into: cylindrical roller bearings ----- rolling body is cylindrical roller bearings, cylindrical roller ratio of length to diameter of less than or equal to.
