The joint bearing is a special structure sliding bearing. Its structure is simpler than the rolling bearing. It is mainly composed of an inner sphere with an outer sphere and an outer ring with an inner sphere. It can bear a large load. According to its different types and structures, it can bear the joint load of radial load, axial load or radial and axial. Joint bearings are generally used for low speed swinging motion (angular motion). Because the sliding surface is spherical and can also be tilted in a certain angle range, it can still work normally when the degree of inconcentricity of the supporting axis and the shaft shell is large.
The joint bearing 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. Since the composite material is embedded on the outer spherical surface of the inner ring, the bearing can produce self lubrication in operation. Generally used for low speed swing motion and low speed rotation, when the supporting shaft and axle housing hole have greater concentricity, they can still work normally. Self lubricating joint bearings are used in water conservancy, professional machinery and other industries. The joint bearing is mainly composed of an inner ring with an outer spherical surface and an outer ring with an inner spherical surface.
