Joint bearing is a kind of spherical sliding bearing, whose sliding contact surface is an inner sphere and an outer sphere, which can rotate and swing at any Angle when moving. It is made of surface phosphating, blasting, padding, spraying and other special processing methods. Joint bearing has the characteristics of large load capacity, impact resistance, corrosion resistance, wear resistance, only aligning, good lubrication and so on.
Joint bearings can bear large loads. According to its different types and structures, it can bear radial load, axial load or radial and axial load. Because the outer sphere of the inner ring is inlaid with composite material, the bearing can be self-lubricating in operation. Generally used for low speed swing movement, and low speed rotation, can also be in a certain range of Angle tilt movement, when the supporting shaft and shaft shell hole concentricity is large, it can still work normally. Self-lubricating joint bearings are used in water conservancy, professional machinery and other industries.
Joint bearings are widely used in engineering hydraulic cylinders, forging machine tools, construction machinery, automation equipment, automotive shock absorbers, hydraulic machinery and other industries.
The knuckle bearing is a spherical sliding bearing. The basic type is composed of an inner ring and an outer ring with a spherical sliding spherical contact surface. Depending on its structure and type, it can bear radial load, axial load, or the combined load of radial and axial action at the same time.
