Product Details
Bimetal Bearings , Low Carbon Steel Wth CuSn10Pb10
CuSn10Pb10 Bimetal Bearings is backed with high quality low carbon steel with Tin-Lead-Bronze
alloy (CuSn10Pb10) sintered on its surface. To effectively decrease
abrasion, CuSn10Pb10 Bimetal Bearings' alloy surface can be machined with ball oil sockets for easier oil
storage. When necessary, an anti-erosive coating can be plated on
the steel back. CuSn10Pb10 Bimetal Bearings can be applied to conditions of mediate load with mediate or high
running velocity and conditions with enormous impact load. In
mechanical application, CuSn10Pb10 Bimetal Bearings is used to make wrapped bushes, thrust washer and bushes on
connecting rod level of gas engine, etc.
