Joint bearing is spherical sliding bearing rod end bearing: 

The basic type is composed of inner and outer rings with spherical sliding spherical contact surface.

Joint bearing is mainly composed of an inner ring with an outer sphere and an outer ring with an inner sphere, which can bear a larger load.

According to its different types and structures, it can withstand radial load, axial load or combined load with both radial and axial loads.

Since the composite material is embedded on the outer spherical surface of the inner ring, the bearing can produce self-lubrication in operation.

Generally, it is used for swing motion with low speed and inclined motion in a certain angle range. When the support shaft is not concentric with the shaft shell hole, it can still work normally.

Application:

Self-lubricating joints are used in water conservancy, professional machinery and other industries.

Process:

Because the spherical sliding contact area of the joint bearing is large and the inclination angle is large, at the same time, most of the joint bearings adopt special processing methods, such as surface phosphating, galvanizing, chromium plating or outer sliding surface lining, padding, spraying and so on.

Advantage:

Therefore, it has greater load capacity and impact resistance, and has the characteristics of corrosion resistance, wear resistance, self-alignment, good lubrication or self-lubrication without lubrication pollution. It can work normally even if it is misplaced. Therefore, joint bearings are widely used in low speed swing motion, tilt motion and rotation motion.
