The spherical plain bearing is a spherical sliding bearing. Its sliding contact surface is an inner spherical surface and an outer spherical surface. It can rotate and swing at any angle during movement. It adopts surface phosphating, frying, inlaying, spraying and other special processes. Method made. Joint bearings have the characteristics of large load capacity, impact resistance, corrosion resistance, wear resistance, self-aligning and good lubrication.
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 rotational motion.
