Rod is a special structure of the sliding bearings. Its simple structure than the rolling bearing, which is mainly an inner and outer sphere within a spherical outer ring, can withstand a greater load, according to their different types and structures that can withstand the radial load, axial to load or radial, axial joint load simultaneously. Bearings are generally used for lower-speed swing motion (ie angular motion), the sliding surface of the spherical shape, but also for a certain tilt angle range of motion (ie, self-aligning movement), the bearing hole axis and the axis of the shell of different heart large degree, still work. Bearings are widely used in hydraulic engineering, metal forming machine, construction machinery, automation equipment, automotive shock absorbers, water and machinery. Introduction and classification of joint bearing joint bearing is spherical plain bearings, spherical basic model is by a sliding spherical contact with surface, the outer ring. According to its structure and type, can withstand the radial load, axial load, or radial, axial joint load acting simultaneously. Because of the spherical plain bearings sliding contact area, a large tilt angle, and also because most of the articular bearing to a special treatment process, 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 with anti-corrosion, abrasion-resistant, self-aligning, self lubricating lubrication or no lubrication good dirt pollution characteristics, even if the dislocation can be installed to work. Therefore, the joint bearings are widely used in lower-speed swing motion, tilt and rotation movement. Electrical Co., Ltd.
