Oil-free bushing is an improvement of copper bushing. In design, oil-free bushing will be selected if light load. Oil-free bearings are generally used under low load and low speed 1000 rpm.
Most of the oil-free bushings are now steel sheets, intermediate sintered spherical bronze powder, and sprayed with other materials, such as a mixture of polytetrafluoroethylene (PTFE) and lead. It has the characteristics of small friction coefficient, good wear resistance, corrosion resistance and oil-free lubrication. It is mostly used in sliding parts of various machines, such as printers, textile machines and hydraulic conveyors for fitness machines. Some sleeves are processed by special technology and can withstand high-speed movement, but can not withstand heavy loads.
Bearing is an important part of modern mechanical equipment. Its main function is to support the mechanical rotating body, reduce its friction coefficient in the process of motion, and ensure its accuracy.
