Application of spherical plain bearings

Spherical plain bearings are a special type of plain bearing. Its structure is simpler than rolling bearings. It consists mainly of an inner ring with an outer spherical surface and an outer ring with an inner spherical surface. It can withstand large loads. According to its different types and structures, it can withstand radial loads and shafts. Combined load to load or radial and axial simultaneously. Spherical plain bearings are generally used for low-speed oscillating motion (ie, angular motion). Since the sliding surface is spherical, it can also be tilted within a certain range of angles (ie, aligning motion), and the support shaft is different from the shaft hole. When the heart is large, it still works normally.

Spherical plain bearings are widely used in engineering hydraulic cylinders, forging machine tools, engineering machinery, automation equipment, automobile shock absorbers, hydraulic machinery and other industries. Spherical plain 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 withstand radial loads, axial loads, or combined loads acting in both radial and axial directions. Because the spherical sliding contact area of the joint bearing is large, the inclination angle is large, and because most of the joint bearings adopt special processing methods, such as surface phosphating, galvanizing, chrome plating or outer sliding surface lining, inserting, spraying and the like. Therefore, it has large load capacity and impact resistance, and has the characteristics of corrosion resistance, wear resistance, self-aligning, good lubrication or self-lubricating and non-lubricating dirt pollution, even if the installation is misplaced, it can work normally. Therefore, joint bearings are widely used for low-speed oscillating motions, tilting motions, and rotational motions.
