Spherical bearings can withstand large loads. According to its different types and structures, it can bear radial load, axial load or radial and axial combined load. Due to the composite material inlaid on the outer spherical surface of the inner ring, the bearing can produce self-lubrication during operation. It is generally used for low-speed swing motion and low-speed rotation, and can also be tilted within a certain angle range. When the support shaft and the shaft housing hole have a large concentricity, it can still work normally. Self-lubricating spherical plain bearings are used in industries such as water conservancy and professional machinery.
Because the spherical sliding contact area of the spherical bearing is large and the inclination angle is large. At the same time, most spherical bearings adopt special processing methods, such as surface phosphating, galvanizing, chrome plating or outer sliding surface lining, inlay, spraying, etc. Therefore, it has a large load capacity and impact resistance, and has the characteristics of corrosion resistance, wear resistance, self-alignment, good lubrication, or self-lubrication without lubrication pollution, and can work normally even if the installation is misplaced. Therefore, articulated bearings are widely used for low-speed oscillating motion, tilting motion and rotary motion.
Articulated bearings are widely used in engineering hydraulic oil cylinders, forging machine tools, construction machinery, automation equipment, automobile shock absorbers, hydraulic machinery and other industries. Spherical plain bearings are spherical plain bearings. The basic type consists of inner and outer rings with a spherical sliding spherical contact surface. According to its structure and type, it can bear radial load, axial load, or combined load acting simultaneously in radial and axial directions.
