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 generate 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 degree of misalignment, it can still work normally.
Joint bearings are widely used in engineering hydraulic cylinders, forging machine tools, engineering machinery, automation equipment, automotive shock absorbers, water conservancy machinery and other industries. Introduction and classification of joint bearings The inner and outer ring composition. Depending on its structure and type, it can bear radial load, axial load, or a combined load that acts simultaneously on the 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 bearing adopts 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 for low-speed swing motion, tilt motion and rotation motion
