Bearing joint is a type of rod end joint bearing

Rod end bearing joint is a type of joint bearing with or mounted on the rod end, which belongs to the category of bearing joint.Joint bearing are spherical sliding bearings, which are basically composed of inner and outer rings with spherical sliding spherical contact surfaces. Joint bearing joint are mainly composed of an inner ring with an outer spherical surface and an outer ring with an inner spherical surface, which can withstand large loads. According to its different types and structures, it can withstand radial loads, axial loads, or combined loads that exist both radially and axially. Due to the composite material embedded on the outer spherical surface of the inner ring, this bearing joint can generate self-lubricating during operation.

It is generally used for swinging movements with lower speeds, and can also be tilted within a certain angle range. When the support shaft and the shaft shell hole are not concentric, it can still work normally. Self lubricating joint support is applied in industries such as water conservancy and professional machinery.
Due to the large spherical sliding contact area and inclination angle of joint bearing joint, as well as the fact that most joint bearings adopt special processing methods such as surface phosphating, galvanizing, chrome plating, or external sliding surface lining, pad insertion, spraying, etc.

Therefore, it has a large load capacity and impact resistance, and has the characteristics of corrosion resistance, wear resistance, self centering, good lubrication or self-lubricating without lubricating dirt pollution. Even if installed incorrectly, it can work normally. Therefore, joint bearing joint are widely used in lower speed swing, tilt, and rotation movements.
Spherical joint and rod end joint bearings have multiple designs and different combinations of sliding contact surfaces. Each design and combination has unique performance, making it particularly suitable for certain application scenarios.
