SKF Joint bearing

The structure of plain bearing is simpler than that of rolling bearing. It is mainly composed of an inner ring with outer sphere and an outer ring with inner sphere. The plain bearing is generally used for low-speed swing motion (i.e. angular motion). Because the sliding surface is spherical, it can also make inclined motion (i.e. centering motion) within a certain angle range. It can still work normally when the non concentricity between the support shaft and the shaft shell hole is large

features
plain bearings can bear large loads. According to its different types and structures, it can bear radial load, axial load or combined radial and axial load at the same time. Because the outer spherical surface of the inner ring is inlaid with composite materials, the bearing can produce self lubrication in operation. It is generally used for low-speed swing movement and low-speed rotation. It can also make inclined movement within a certain angle range. It can still work normally when the non concentricity between the support shaft and the shaft shell hole is large. Self lubricating plain bearings are used in water conservancy, professional machinery and other industries

Application
self lubricating spherical plain bearings
spherical plain bearings are widely used in engineering hydraulic cylinders, forging machine tools, engineering machinery, automation equipment, automobile shock absorbers, hydraulic machinery and other industries. Plain bearings are spherical plain bearings. The basic type is composed of inner and outer rings with spherical sliding spherical contact surfaces. According to its structure and type, it can bear radial load, axial load, or combined load acting both radially and axially

because the spherical sliding contact area of the joint bearing is large and the inclination angle is large, and because most of the joint bearings adopt special process treatment methods, such as surface phosphating, galvanizing, chromium plating or outer sliding surface lining, insert pad, spraying, etc., they have large load capacity and impact resistance, corrosion resistance, wear resistance, self-aligning It has the characteristics of good lubrication or self lubrication without lubrication dirt pollution, and can work normally even if it is installed incorrectly. Therefore, articulated bearings are widely used in low-speed swing motion, tilt motion and rotary motion

composition
plain bearing is mainly composed of an outer ring and an inner ring. The inner spherical surface of the outer ring and the outer spherical surface of the inner ring form a rolling friction pair
