Steel ( DIN-St12|ASTM-A366/A366M-97|JIS-SPCC ) + PTFE + Fibre Introduction PTFE fibre fabric self-lubricating bearings(steel), made of low carbon steel, are produced by the process of being sticked PTFE fibre as self-lubricating material. They are in conformity with the European RoHS environmental protection standards and widely used in the applications of automotive, truck and engineering machinery due to the advantages of lead free, low friction coefficient, good self-lubricating,good wear resistance and good load capacity.
