Overview of Joint bearing
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.
The structure of the joint bearing is simpler than that of the rolling bearing. It 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 swing motion ( angular motion). Because the sliding surface is spherical, it can also be tilted within a certain angle range ( self-aligning motion). The support shaft and the shaft housing hole are not concentric. When the temperature is high, it can still work normally.Here is an introduction about outer spherical ball bearings.

Features
Joint bearings can withstand larger loads. According to its different types and structures, it can bear radial load, axial load or a combined load of both radial and axial. Since the outer spherical surface of the inner ring is inlaid with composite materials, the bearing can generate 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 support shaft and the shaft housing hole have a large misalignment, it can still work normally. Self-lubricating joint bearings are used in water conservancy, professional machinery and other industries.
Composition
The joint 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.
Application
Joint bearings are widely used in engineering hydraulic cylinders, forging machine tools, engineering machinery, automation equipment, automotive shock absorbers, water conservancy machinery and other industries. Joint bearings are spherical sliding bearings, 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 a combined load that acts simultaneously on the radial and axial directions.
