Application：
         Joint bearings are widely used in engineering hydraulic cylinders, forging machine tools, engineering machinery, automation equipment, automotive shock absorbers, water conservancy machinery and other industries. The joint bearing is a spherical plain bearing, and the basic type is composed of inner and outer rings having a spherical sliding spherical contact surface. Depending on its structure and type, it can withstand radial loads, axial loads, or combined loads acting in both radial and axial directions.

        Because the spherical sliding contact area of the joint bearing is large, the inclination angle is large, and also because most joint bearings adopt special processing methods, such as surface phosphating, galvanizing, chrome plating or outer sliding surface lining, inserting, spraying, etc. Therefore, it has large load capacity and impact resistance, and has the characteristics of corrosion resistance, wear resistance, self-aligning, good lubrication or self-lubricating and non-lubricating dirt pollution, even if the installation is misplaced, it can work normally. Therefore, joint bearings are widely used for low-speed oscillating motions, tilting motions, and rotational motions.
