The joint bearing is mainly composed of an inner ring with an outer spherical and an outer ring with inner sphere, which can withstand a large load. According to its different types and structures, a combination load that exists at the same time of radial load, axial load or radial, and axis. Since the outer side of the inner ring is inlaid with composite materials, the bearing can produce self -lubrication during work. It is generally used for lower swing movements, and it can also be tilted within a certain angle range. When the support of the bracket shaft and the axis case is different, it can still work normally. Self -lubricating joints are applied to water conservancy, professional machinery and other industries.
Joint bearing is widely used in engineering hydraulic oil cylinders, forging machine tools, engineering machinery, automated equipment, automotive shock absorbers, water conservancy machinery and other industries. Introduction to joint bearing and classification joint bearing are spherical skating bearing. Inner and outer circle composition. Depending on the structure and type, the radial load, axial load, or the combined load that acts at the same time of radial and axis. Because the spherical sliding contact area of the joint bearing is large, the tilt angle is large, and it is also adopted by most joint bearing to adopt special process treatment methods, such as surface phosphate, galvanizing, chrome or external sliding surface lining, spraying, etc. Therefore, it has a large load capacity and impact resistance, and has the characteristics of resistance to corrosion, abrasion resistance, self -adjustment, lubricating or self -lubricating pollution pollution, and can work normally even if it is installed dislocated. Therefore, joint bearing is widely used for low -speed swing movement, tilt motion and rotation movement.
Imported arthritis, such as SB, CF types, GE types, etc., as well as a certain number and other types of other types of cardiac bearing, rod end -end bearing, etc.
