  • Spherical plain bearings 

    Spherical plain bearings is a kind of spherical sliding bearing. Its sliding contact surface is an inner spherical surface and an outer spherical surface. It can rotate and swing at any angle when moving. It is made by many special processing methods, such as surface phosphating, explosion opening, inserting pad, spraying and so on.



    • Load capacity,

    • Impact resistance,

    • Corrosion resistance,

    • Wear resistance ,

    •  Self-aligning,

    • Good lubrication


    Spherical plain bearings can withstand large loads. 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 used for low-speed swing motion, low-speed rotation, can also be tilted within a certain angle range, when the support shaft and the shaft shell hole are not concentric enough, it can still work normally. Self-lubricating joint bearings are used in water conservancy, professional machinery and other industries.

Self-aligning ball bearings have two rows of balls, a common sphered raceway in the outer ring and two deep uninterrupted raceway grooves in the inner ring
