SPHERICAL PLAIN BEARING

The joint bearing is a special structure of the sliding bearing, its structure is more simple than the rolling bearing, which is mainly composed of an outer sphere with an outer sphere and a outer ring with an inner sphere, which can bear a large load. According to its different type and structure, it can bear the combined load of radial load, axial load or radial and axial coexistence. Generally used for low speed swing motion (angular motion). Because the sliding surface is a spherical type, it can also be inclined motion in a certain angle range (that is, the movement of the center of the center). When the degree of inconcentricity of the supporting axis and the axle housing hole is large, the pole can work normally.
According to the direction of the load, the nominal contact angle and the structure form, the joint bearing can be divided into the concentric joint bearing, the angular contact joint bearing, the thrust joint bearing and the rod end bearing.
The bearings on the sliding surfaces of the joint bearings are lubricated with self lubricating joint bearings.
