The structure of the joint bearing is simpler than that of the rolling bearing. It is mainly composed of an inner ring with an outer spherical surface and an outer ring with an inner spherical surface. Joint bearings are generally used for low-speed swing motion (ie angular motion). Because the sliding surface is spherical, it can also be tilted within a certain angle range (ie, centering motion). The support shaft and the shaft housing hole are not concentric. When the temperature is large, it can still work normally.

Features:

Joint bearings can withstand larger loads. According to its different types and structures, it can bear radial load, axial load or a combined load of both radial and axial. Since the outer spherical surface of the inner ring is inlaid with composite materials, the bearing can produce self-lubrication during operation. It is generally used for low-speed swing motion and low-speed rotation. It can also be used for tilting motion within a certain angle range. When the support shaft and the shaft housing hole have a large misalignment, it can still work normally. Self-lubricating joint bearings are used in water conservancy, professional machinery and other industries.

application:

Joint bearings are widely used in engineering hydraulic cylinders, forging machine tools, engineering machinery, automation equipment, automotive shock absorbers, hydraulic machinery and other industries. Joint bearings are spherical sliding bearings. The basic type is composed of inner and outer rings with spherical sliding spherical contact surfaces. Depending on its structure and type, it can bear radial load, axial load, or a combined load that acts on both radial and axial directions.

Because the spherical sliding contact area of the spherical plain bearing is large, the inclination angle is large, and also because most of the spherical plain bearings adopt special processing methods, such as surface phosphating, galvanizing, chrome plating or outer sliding surface lining, inserting, spraying, etc. Therefore, it has a large load capacity and impact resistance, and has the characteristics of corrosion resistance, wear resistance, self-aligning, good lubrication or self-lubricating without lubricating dirt pollution, and it can work normally even if the installation is misplaced. Therefore, joint bearings are widely used in low-speed swing motion, tilt motion and rotation motion.
