Cylindrical plain bearing IB014

bronzesintered bronzestainless steel

Material Stainless Steel ( DIN-X5CrNiL8 9|AISI 304| JIS-SUS304 ) + Bronze ( CuSn8Zn3 ) + PTFE Introduction Dry bearings(stainless steel/black PTFE), made of stainless steel as base material, are produced by the process of being sintered bronze powder as medium layer and coated PTFE as lubrication layer. They are in conformity with the European RoHS environmental protection standards and widely used in the applications of automotive, bicycle, hydraulic transmission, shipping and chemical equipment due to the advantages of lead free, low friction coefficient, good self-lubricating, good wear resistance and good corrosion resistance.
