Overview of joint bearings

Definition of joint bearings

Joint bearings are mainly composed of an inner ring with an outer sphere and an outer ring with an inner sphere, which can bear a large load.Depending on its type and structure, it can bear radial load, axial load or a combination of radial and axial loads.Because the outer sphere of the inner ring is inlaid with composite material, the bearing can produce self-lubrication in operation.Generally used for low speed swing movement, but also in a certain Angle range for inclined movement, when the supporting shaft and shaft shell hole is not concentricity is large, it can still work normally.

Application of joint bearings

Joint bearings are widely used in engineering hydraulic cylinders, forging machine tools, construction machinery, automation equipment, automotive shock absorbers, water conservancy machinery and other industries.Spherical plain bearings are spherical plain bearings, the basic type is composed of an inner and 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 simultaneously.

Characteristics of joint bearing

The sliding contact surface of plain bearings 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 bearings have the characteristics of large load capacity, impact resistance, corrosion resistance, wear resistance, self-aligning, good lubrication and so on.

Because joint bearing spherical sliding contact area is large, slope Angle is large, but also because most of the joint bearing adopted special processing methods, such as surface phosphating, galvanized, chrome plating, or outside sliding surface lining, padded, spraying, etc., so the larger load capacity and impact resistant ability, and have the corrosion resistance, wear resistance, can make, good lubrication and self-lubricating without lubrication characteristics of sewage pollution also can work normally even install dislocation.Therefore, joint bearings are widely used in low speed swing motion, tilt motion and rotary motion.
