Joint bearing is a kind of sliding bearing with special structure. Its structure is simpler than the rolling bearing, which is mainly composed of an inner ring with an outer sphere and an outer ring with an inner sphere, which can bear a large load

According to its different types and structures, it can bear radial load, axial load or radial and axial combined load. Since the outer sphere of the inner ring is embedded with composite material, the bearing can produce self-lubrication in work. Generally used for low speed swing motion, and low speed rotation, can also be in the range of *** Angle for tilt motion, when the supporting shaft and shaft shell hole concentricity is larger, can still work normally. Self-lubricating joint bearings are used in water conservancy, machinery and other industries
