With bronze wire mesh as matrix body, FR PTFE Soft Belt Bearing is coated with PTFE and other filling and abrasion-resisting materials, featuring good abrasion resistance. It can be used as the diaphragm for steel bearings an features no gap, no operating noise, oilless lubrication, maintenance free and pollution free. It has been extensively used for joints of textile machinery, automotive door hinge, and automotive control stick, and so on.
