PTFE Fiber
Introduction
Engineering plastic bearings, made of high strength glass fiber and epoxy resin as base material, are produced by the process of being winded special PTFE fiber as lubrication layer. They are in conformity with the European RoHS environmental protection standards and widely used in the applications of truck and engineering machinery due to the advantages of lead free, low friction oefficient, good self-lubricating, good wear resistance, good corrosion resistance and good load capacity.
