What is a joint bearing

Introduction to Joint Bearings Joint bearings are a special type of sliding bearing with a special structure. Its structure is simpler than rolling bearings. It mainly consists of an 

inner ring with an outer spherical surface and an outer ring with an inner spherical surface, which can withstand large loads. Depending on its different type and structure, it 

can withstand radial loads, axial loads, or combined loads that exist both radially and axially. Joint bearings are generally used for low-speed swinging motion (i.e. angular 

motion). Due to the spherical sliding surface, they can also perform tilting motion (i.e. centering motion) within a certain angle range. They can still work normally when the 

supporting shaft and the shaft shell hole are not concentric enough.

The characteristics of joint bearings: Joint bearings can withstand large loads. According to its different types and structures, it can withstand radial loads, axial loads, or 

combined loads that exist both radially and axially. Due to the composite material embedded on the outer spherical surface of the inner ring, this bearing can generate self-

lubricating during operation. It is generally used for low-speed swing motion, low-speed rotation, and can also perform tilting motion within a certain angle range. When 

the support shaft and the shaft shell hole are not concentric, it can still work normally. Application of self-lubricating joint support in industries such as water conservancy 

and professional machinery

The application of joint bearings is widely used in engineering hydraulic cylinders, forging machines, construction machinery, automation equipment, automotive shock 

absorbers, water conservancy machinery and other industries Introduction and classification of joint bearings Joint bearings are spherical sliding bearings, which are basically 

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 both radially and axially. Due to the large spherical sliding contact area and inclination angle of joint bearings, as well as the fact that most joint bearings adopt 

special processing methods such as surface phosphating, galvanizing, chrome plating, or external sliding surface lining, pad insertion, spraying, etc. Therefore, it has a large 

load capacity and impact resistance, and has the characteristics of corrosion resistance, wear resistance, self centering, good lubrication or self-lubricating without lubricating 

dirt pollution. Even if installed incorrectly, it can work normally. Therefore, joint bearings are widely used for lower speed swing, tilt, and rotation movements.Joint bearing
