ATC311 Material Composition

ATCORP, ATC-311 Bimetal bearing material is a sliding bushing with steel Backing and a CuSn10Bi3 surface sliding layer. It is ELV, ROHS Compliance material.Suitable for fat or oil lubrication, lower friction factor, Shock and vibration resistance, good lubricity and wear resistance. Oil holes, oil holes or oil tanks can be set The sliding layer can be refined to improve the matching accuracy. Suitable for high load and medium speed conditions.These sliding bushings are used in applications with high Loads and medium speeds .Steel Backing provides strength to Bimetal structure while soft Sliding layer of CuSn10Bi3 helps to improve lubrication with strong wear resistant properties. Can be set in oil holes, grease indents or oil pockets.ATC-311 Material comes with three options like tin flash, copper flash or Zn Flashing also to avoid rusting of steel during transit /storage
