Self-lubricating requirements and structural advantages of rod end joint bearing

- Mar 13, 2019-

Rod end joint bearing can withstand relatively large loads when in use, and can be subjected to radial loads, axial loads or combined radial and axial loads during operation depending on their type and structure. . Since the outer surface of the inner ring is provided with a composite material, the bearing can be self-lubricated during operation.


Rod end joint bearings are generally used for low-speed oscillating motion, and low-speed rotation, and can also be tilted within a certain range of angles. When the support shaft and the shaft housing hole are different in center of gravity, they can still work normally. Self-lubricating joint bearings are used in water conservancy and professional machinery industries.


Rod end joint bearings are widely used in engineering hydraulic cylinders, forging machine tools, engineering machinery, automation equipment, automobile 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.
