Impact resistance and process treatment of tie rod end bearings

- Aug 26, 2019-

The tie rod end bearing is a spherical plain bearing. The basic type of the rod end bearing is composed of inner and outer rings with a spherical sliding spherical contact surface. The rod end bearing is mainly composed of an inner ring with an outer spherical surface and an inner spherical surface. The ring is composed 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.


In general, the rod end bearing can be tilted in a certain angle range due to the lower speed swinging motion. When the supporting shaft and the shaft shell hole are different in center of gravity, the cable 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.


The drawbar end bearing therefore has a 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, and can work normally even if the installation is misaligned. Therefore, joint bearings are widely used for low-speed oscillating motions, tilting motions, and rotational motions.
