Backing bearings outer ring has a special structure

Plain Backing bearings mainly by an inner and an outer spherical plain bearing outer ring has a special structure within the sphere. Can withstand a greater load. Joint bearing structure than simply rolling bearing, which is mainly composed of an inner and outer sphere within a spherical outer ring. Bearings are generally used for lower-speed swing motion (ie angular motion), Backing Bearings the sliding surface of a spherical shape, but also for tilting movement within a certain range of angles (ie, aligning movement), different heart in supporting shaft and shaft housing bore large degree, still working properly. Spherical plain bearings can withstand a greater load. double row cylindrical roller bearing According to their different types and structures that can withstand the radial load, Backing bearings axial load or radial, axial joint load. Since the outer spherical surface of the inner ring inlaid with composite materials, so the bearing at work can produce self-lubricating. Generally used for slower swing movement, and low-speed rotation, but also for tilting movement within a certain range of angles, when different supporting shaft and shaft misalignment large shell hole, still work. Self-lubricating bearings used in water conservancy, specialized machinery and other industries.
