Bimetal Thrust Washer , Low Carbon Steel Wth CuPb24Sn
CuPb24Sn Thrust Washer is backed with high quality low carbon steel with Tin-Lead-Bronze alloy (CuPb24Sn) sintered on its surface.
CuPb24Sn Thrust Washer is with very high fatigue-resistance, load capacity, excellent surface property.
To effectively decrease abrasion, CuPb24Sn Thrust Washer's 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, CuPb24Sn Thrust Washer is mainly used in main shaft and con rod shaft of internal combustion engine.
