HLDB-80G bimetal bushing is backed with high quality low carbon steel with tin-lead-bronze alloy(CuSn10Pb10)sintered on its surface. To effectively decrease abrasion, its alloy surface can be machined with ball shaped oil sockets for easier oil storage. When necessary, it could be plated copper or tin on the steel back. It can be applied to conditions of mediate load with mediate or high running belocity and conditions with enormous impact load. In mechanical applications, HLDB-80G is used to make wrapped bushes, thrust washer and bushes on connecting rod level of gas engine
