Process treatment and impact resistance of rod end joint bearings

- Aug 27, 2018-

The basic type of rod end joint bearing is composed of inner and outer rings with spherical sliding spherical contact surface. It can withstand relatively large loads during operation. According to its different types and structures, it can withstand radial load, axial load or radial, Combined load that exists simultaneously in the axial direction.

Rod end joint bearings will be self-lubricated during operation due to the composite material on the outer spherical surface of the inner ring. Generally, it will be used for lower speed swing motion or within a certain angle range. For the tilting movement, when the support shaft and the shaft hole are different in center of gravity, 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.

Due to its large load capacity and impact resistance, the rod end joint bearing has the characteristics of corrosion resistance, wear resistance, self-aligning, lubrication or self-lubricating and non-lubricating dirt during operation, even if the installation is misaligned. Can work normally. Therefore, joint bearings are widely used for low-speed oscillating motions, tilting motions, and rotational motions.
