Characteristics and Applications of spherical plain bearings

Aug 30, 2021

Joint bearing is a kind of spherical sliding bearing. Its sliding contact surface is an inner sphere and an outer sphere. It can rotate and swing at any Angle when moving. Joint bearing has the characteristics of large load capacity, impact resistance, corrosion resistance, wear resistance, self-aligning, good lubrication and so on.

Joint bearings are widely used in engineering hydraulic cylinders, forging machine tools, construction machinery, automation equipment, automobile shock absorbers, water conservancy machinery and other industries. The joint bearing is a spherical plain bearing. The basic type is composed of an inner and outer ring with a spherical sliding spherical contact surface. Depending on its structure and type, it can bear radial load, axial load, or radial and axial combined load simultaneously.

Because the spherical sliding contact area of joint bearings is large and the inclination Angle is large, but also because most of the joint bearings adopt special processing methods, such as surface phosphating, galvanizing, chrome plating or outer sliding surface lining, insert pad, spraying, etc., so they have a large load capacity and impact resistance. And has the characteristics of corrosion resistance, wear resistance, self-aligning, good lubrication or self-lubrication without lubrication dirt pollution, even if the installation dislocation can work normally. Therefore, joint bearings are widely used in low speed swing motion, tilt motion and rotary motion.
