Spherical Plain Bearings

 Slewing bearing are widely used in hydraulic engineering, metal forming machine tools, engineering machinery, automation equipment, automotive shock absorbers, irrigation machinery and other industries. Introduction and classification of joint bearing joint bearing is spherical plain bearings, the basic model is made with a sliding spherical contact surface the inner and outer components. According to its structure and type, can bear radial load, axial load, or radial, axial joint load acting simultaneously. Because of the spherical plain bearings sliding contact area, tilt angle is large, but also because most of the bearings taken a special treatment process methods, such as surface phosphating, zinc, chrome or outer sliding surface lining, insert pads, spraying. Therefore, greater load capacity and impact resistance, and has anti-corrosion, abrasion, self-aligning, self-lubricating lubrication better or no lubrication contaminating features, even if the installation dislocation can also work. Therefore, joint bearings are widely used for slower swing motion, tilt and rotation movement
