Joint bearing is spherical plain bearing, the basic type is composed of a spherical sliding spherical contact surface, the outer ring. Joint bearing is mainly composed of a spherical inner ring and aspherical outer ring, can bear larger load. According to the different types and structures, can be combined with the load bearing radial load, axial load and radial, axial exist at the same time.
Because of the spherical inner ring with a composite material,so the bearing in the work can generate self lubrication. The general swing motions are used for low speed, can also be used as the tilt movement in a certain range, when the bearing shaft and the shaft shell hole not concentricity is larger, can still work normally. Self lubricating joint auxiliary bearing used in water conservancy, major in mechanical industry. Because the spherical sliding contact area of joint bearing, tilt angle, but also because most of the joint bearing the process special processing methods,such as surface phosphating, galvanized, chrome plated or outside the sliding surface lining, pad, spray. So there is a larger load capacity and impact resistance, and corrosion resistance, wear resistance, self aligning, good lubrication or self lubricating oil-freedirt pollution, even if the installation misalignment can work normally. Therefore, the joint bearing is widely used in swing motion, the lower velocity tilt motion and rotary motion.
Spherical plain bearing and rod end joint bearing a variety of designs, and the sliding contact surface combination of different.Has the unique properties of each design and combination, make it particularly suitable for certain applications.

To choose a certain type of bearing, to determine the bearing sizerequired, the main factors that must be considered is the load, the load bearing capacity and life expectancy. Select the rod end joint bearing, and so.
The type required by GB/T9161 standards can be divided into:bending rod ball joint rod end joint bearing (type code: SQ);straight rod ball joint rod end bearings (type code: SQZ); single rodball joint rod end bearings (type code: SQD); left internal thread assembling rod end joint bearing (type Code: SLLB); left outer thread assembling rod end joint bearing (type code: SALB); leftbending rod rod end joint bearing (type code: SLLB); a single rodrod end joint bearing (type code: SQLD); with cylindrical weldingrod end joint bearing (cylindrical) (type code: SK); with flat seat welding rod end joint bearing (Fang Xing) (type code: SF); lockingtype rod end joint bearing (type code: SLR).
