Characteristics and application of joint bearing

The structure of the joint bearing is simpler than that of the rolling bearing, and it mainly consists of an inner ring having an outer spherical surface and an outer ring having an inner spherical surface. Joint bearings are generally used for low-speed oscillating motion (ie angular motion). Since the sliding surface is spherical, it can also be tilted in a certain range of angles (ie, aligning motion), and the support shaft is not concentric with the shaft hole. When the degree is large, it still works normally.

Features:
       Joint bearings can withstand large loads. Depending on their type and construction, it is possible to withstand radial loads, axial loads or combined loads of radial and axial forces. Since the outer surface of the inner ring is provided with a composite material, the bearing can be self-lubricated during operation. Generally used for low-speed oscillating motion, and low-speed rotation, it can also be tilted within a certain angle range. When the support shaft and the shaft housing hole are different, the normal operation can still be performed. Self-lubricating joint bearings are used in water conservancy and professional machinery industries.
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.
