Bimetal Bushing Material CuPb10Sn10, SAE-797 Bronze Alloy Bearings,Sintered SAE797 Layer + Steel Backing + Copper Plating / Tin-Plating made to order from china manufacturer.Bimetal Bushing with Oil Grooves. The bimetal sliding bearings are produced on a steel base, with sintered CuPb10Sn10 or CuSn6Zn6Pb3 as the surface sliding layer.
Wrapped composite sliding bearing, steel / bronze - Bimetal Bushings
This type of sliding bearing has the best characteristics of all bimetal sliding bearings. They can be used with balancing suspension devices for heavy commercial vehicles, bulldozer wheels and car chassis, among other equipment. They are ideally suited to medium speed ranges and applications with high shock and impact forces.

1, A mid-load capacity & middle anti-fatigue
2. Applied in middle speed, high impact conditions.
3. Good anti-corrosion, and sliding capability.
4. the products can be used in undercarriage parts and engines of auto industry, constrution machine etc.
Steel＋CuPb10Sn10
VSB-80 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, VSB-80 is used to make wrapped bushes, thrust washer and bushes on connecting rod level of gas engine.
