The structure of the spherical plain bearing is simpler than that of the rolling bearing, which is mainly composed of an inner ring with an outer spherical surface and an outer ring with an inner spherical surface. Joint bearings are generally used for low-speed swinging motion (ie angular motion). Since the sliding surface is spherical, it can also perform tilting motion (ie self-aligning motion) within a certain angle range. When the degree is large, it can still work normally.

Features
Spherical bearings can withstand large loads. According to its different types and structures, it can bear radial load, axial load or combined radial and axial load at the same time. Since the outer spherical surface of the inner ring is inlaid with composite materials, the bearing can produce 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 misalignment between the support shaft and the shaft housing hole is large, it can still work normally. Self-lubricating spherical plain bearings are used in water conservancy, professional machinery and other industries.

Self-lubricating spherical plain bearings
Spherical bearings are widely used in engineering hydraulic cylinders, forging machine tools, engineering machinery, automation equipment, automotive shock absorbers, water conservancy machinery and other industries. The spherical plain bearing is a spherical sliding bearing, and 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 combined radial and axial loads at the same time.
Because the spherical sliding contact area of the spherical plain bearing is large and the inclination angle is large, and because most of the spherical plain bearings adopt special processing methods, such as surface phosphating, galvanizing, chrome plating or outer sliding surface lining, padding, 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-lubricating without lubrication and dirt pollution, and can work normally even if the installation is misplaced. Therefore, spherical plain bearings are widely used for low-speed oscillating motion, tilting motion and rotational motion.
composition
The spherical plain bearing is mainly composed of an outer ring and an inner ring. The inner spherical surface of the outer ring and the outer spherical surface of the inner ring form a rolling friction pair.
