The rod end 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. The rod end joint bearing is mainly composed of an inner ring having an outer spherical surface and an outer ring having an inner spherical surface, and can withstand a large load. 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, it can also be tilted in a certain range of angles. When the support shaft and the shaft housing hole are different, they can still work normally. Self-lubricating joints are used in water conservancy and professional machinery industries. Because the spherical sliding contact area of the joint bearing is large, the inclination angle is large, and because most of the joint bearings adopt special processing methods, such as surface phosphating, galvanizing, chrome plating or outer sliding surface lining, inserting, spraying and the like. 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.
Spherical plain bearings and rod end joint bearings are available in a variety of designs and have different combinations of sliding contact surfaces. Each design and combination has unique properties that make it ideal for certain applications.www.wxjwbearing.com
