Joint bearing is a type of spherical sliding bearing, with a sliding contact surface consisting of an inner spherical surface and an outer spherical surface. It can rotate and swing at any angle during movement. It is made using various special processing methods such as surface phosphating, blasting, padding, and spraying. Joint bearings have the characteristics of high load capacity, impact resistance, corrosion resistance, wear resistance, self centering, and good lubrication.
Joint bearings are widely used in industries such as engineering hydraulic cylinders, forging machines, construction machinery, automation equipment, automotive shock absorbers, and water conservancy machinery. Joint bearings are spherical sliding bearings, and the basic type consists of an inner and outer ring with a spherical sliding spherical contact surface. Depending on its structure and type, it can withstand radial loads, axial loads, or combined loads of both radial and axial forces.
