Bimetal Bearings with Flange , Low Carbon Steel Wth CuSn4Pb24
CuSn4Pb24 Bimetal Flange Bearings is backed with high quality low carbon steel with Tin-Lead-Bronze alloy (CuSn4Pb24) sintered on its surface.
CuSn4Pb24 Bimetal Flange Bearings is with very high fatigue-resistance, load capacity, impact ability, and corrosion-resistance.CuSn4Pb24 Bimetal Flange Bearings is widely used in main shaft and con rod shaft of internal combustion engine with heavy duty capacity and high speed.
To effectively decrease abrasion, CuSn4Pb24 Bimetal Flange 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 Flange Bearings is widely used in main shaft and con rod shaft of internal combustion engine with heavy duty capacity and high speed.
