Spherical Plain Bearings Overview

Release date:2020-6-14

Joint bearing mainly by a spherical inner ring and an inner spherical outer ring, can withstand a greater load. According to their different types and structures to withstand radial load, axial load or radial, axial joint load. Since the inner surface of the outer sphere inlaid with composite materials, so the bearings can be produced in the work of self-lubricating. Generally used for slower swing movement, but also for a certain tilt angle range of motion, when the bearing shaft and housing bore axis misalignment is large, can still work. Self-lubricating auxiliary bearing joints used in water conservancy, specialized machinery and other industries.

Joint bearings are widely used in hydraulic engineering, metal forming machine tools, engineering machinery, automation equipment, automotive shock absorbers, irrigation machinery and other industries. Introduction and classification of joint bearing joint bearing is spherical plain bearings, spherical basic model is a sliding spherical contact surface The inner and outer ring. Depending on the structure and type, can withstand the radial load, axial load, or radial, axial joint load. Because large spherical plain bearings sliding contact area, tilt angle, but also because most of the articular bearing to a special process treatment, such as surface phosphate, zinc, chrome or outside the sliding surface lining, insert pad, such as spraying. Therefore, greater load capacity and impact resistance, and has anti-corrosion, abrasion-resistant, self-aligning, self-lubricating lubrication or no lubrication good dirt pollution characteristics, even dislocation can be installed to work properly. Therefore, joint bearings are widely used for slower swing motion, tilt movement and rotation.
