1. The sliding bearing
Sliding bearing is not share outer ring no rolling body, are generally made of wear-resistant materials. Often used in low speed, overload and charging mechanical rotating parts of the lubricating oil and maintenance difficulties.
2. Joint bearing
The sliding contact surface for the spherical joint bearing, mainly is suitable for the swing movement, tilted movement and rotation motion.
3. The rolling bearing
Rolling bearing can bear the load according to its direction or nominal contact Angle of divided into radial bearing and thrust bearing. The radial contact bearing as nominal centripetal bearing contact Angle 0, radial angular contact bearings for the nominal contact Angle is greater than 0 to 45 centripetal bearing. Axial bearing is nominal contact Angle is 90 thrust bearing, thrust angular contact bearings for the nominal contact Angle is greater than 45 but less than the thrust bearing of 90.
According to the shape of the roller can be divided into ball bearings and roller bearings. Roller bearing press roller types are divided into: cylindrical roller bearings, needle roller bearings, tapered roller bearing and spherical roller bearing.
According to its work will be adjust when the heart is divided into self-aligning bearing raceway is spherical shape, can adapt to the Angle between the two raceway axis deviation and Angle motion of the bearing and self-aligning bearing (rigid bearing) - can the impedance between the raceway bearing axis Angle deviation.
According to the number of columns of roller is divided into single row bearing, double row bearings and bearing.
According to its components (ring) can be separated into separable bearing and integral bearing.
According to its structure shapes (such as presence of loading slot, with or without inner and outer ring and the shape of a ring, the structure of the guard, even the presence of cage, etc.) can also be divided into a variety of structural types.
