Spherical plain bearings are a type of spherical sliding bearings, with sliding contact surfaces consisting of an inner spherical surface and an outer spherical surface. They can rotate and swing at any angle during movement.
They are made using various special processing methods such as surface phosphating, blasting, pad insertion, and spraying. Joint bearings have the characteristics of high load capacity, impact resistance, corrosion resistance, wear resistance, self aligning, and good lubrication.
