Bronze ( DIN-CuSn8P ) +
PTFE + Fibre
Introduction
PTFE fibre fabric self-lubricating bearings(bronze), made of tin bronze, 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, good thermal conductivity and good load capacity.
