The joint bearing is a spherical sliding bearing, the sliding surface of which consists of inner and outer spheres. It can rotate and swing at any angle while moving. It is manufactured using various special processing methods such as surface phosphorylation, sandblasting, filling and spraying. Joint bearings have high load capacity, impact resistance, corrosion resistance, wear resistance, centering, good lubrication and other characteristics.

Joint bearings are widely used in engineering hydraulic cylinders, forging machines, construction machinery, automatic equipment, automotive shock absorbers, hydraulics and other industries. Joint bearing is a spherical sliding bearing, the main type consists of inner and outer ring with spherical sliding spherical contact. Depending on its structure and type, it can withstand radial load, axial load, or a combination of radial and axial forces.
