Joint bearing

The structure of joint bearings is simpler than rolling bearings, mainly consisting 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 (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. Even when the support shaft and the shaft housing hole are not concentric, they can still work normally.
characteristic
Joint bearings can withstand large loads. According to their different types and structures, they can withstand radial loads, axial loads, or combined loads of both radial and axial loads. Due to the composite material embedded on the outer spherical surface of the inner ring, the bearing can generate self lubrication during operation. It is generally used for low-speed swinging motion and low-speed rotation, and can also perform tilting motion within a certain angle range. When the support shaft is not concentric with the shaft housing hole, it can still work normally. Self lubricating joint bearings are used in industries such as water conservancy and professional machinery.
application
Self-lubricating joint bearing
Joint bearings are widely used in industries such as engineering hydraulic cylinders, forging machines, construction machinery, automation equipment, automotive shock absorbers, and water conservancy machinery. Joint bearings are spherical sliding bearings, and the basic type consists of an inner and outer ring with a spherical sliding spherical contact surface. Depending on its structure and type, it can withstand radial loads, axial loads, or combined loads of both radial and axial forces.
Due to the large spherical sliding contact area and inclination angle of joint bearings, as well as the special processing methods adopted by most joint bearings, such as surface phosphating, galvanizing, chrome plating or outer sliding surface lining, padding, spraying, etc., they have a large load capacity and impact resistance, and have the characteristics of corrosion resistance, wear resistance, self-aligning, good lubrication or self-lubricating without contamination from lubricating dirt. Even if installed incorrectly, they can work normally. Therefore, joint bearings are widely used for low-speed swinging, tilting, and rotating movements.
form
Joint bearings are 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.
