Joint bearing is dominated by an inner and outer sphere within a spherical outer ring , can withstand a greater load. According to their different types and structures that can withstand the radial load, axial load or radial, axial joint load . Since the inner surface of the outer sphere inlaid composite materials, so that the work can be generated in the bearing self-lubricating . Generally used for slower swing movement , but also for the tilt angle within a certain range of motion , when the supporting shaft and shaft misalignment large shell hole , still work properly. Self-lubricating auxiliary bearing joints used in water conservancy , specialized machinery and other industries.
    Bearings are widely used in hydraulic engineering , metal forming machine tools, construction machinery, automation equipment, automotive shock absorbers , irrigation machinery and other industries. Joint bearing joint bearing Introduction and classification of spherical plain bearings , the basic model is made with a sliding spherical contact surface the inner and outer components. Depending on the type of structure and can bear radial load, axial load , or radial, axial joint loads . Because of spherical plain bearing joints large contact area , tilt angle, but also because most of the bearings taken by a special process treatment , such as surface phosphate, zinc , chrome or outside the sliding surface lining, insert pads, spraying. So there is a greater load capacity and impact resistance, and has anti -corrosion , abrasion , self-aligning , self-lubricating without good lubrication or dirt contaminated lubricating characteristics , even if the installation misalignment can work . Therefore , joint bearings are widely used for slower swing motion , tilt and rotational movement .
    Imported bearing joints, such as SB -type , CF type , GE type , as well as a number of models and other types of radial spherical plain bearings, rod end bearings.
