Bimetal Bearings , Low Carbon Steel Wth CuSn4Pb24

CuSn4Pb24 Bimetal Bearings is backed with high quality low carbon steel with Tin-Lead-Bronze alloy (CuSn4Pb24) sintered on its surface.

To effectively decrease abrasion, CuSn4Pb24 Bimetal Bearings' alloy surface can be machined with oil grooves for easier oil storage. When necessary, an erosion protection coating can be plated on the steel back. In common application.

CuSn4Pb24 Bimetal Bearings is used to make wrapped bushes, thrust washer and bushes on connecting rod level of gas engine, etc.

CuSn4Pb24 Bimetal Bearings is widely used in main shaft and con rod shaft of internal combustion engine with heavy duty capacity and high speed.
