Product Description
PVB036 Steel Back CuPb6Sn6Zn3 Bronze Alloy Wrapped Bimetal Bushing
PVB036 wrapped composite bimetal sliding bearing features a steel back with CuPb6Sn6Zn3 bronze alloy layer. The inner bronze alloy surface can be processed with various oil grooves, oil holes, and oil pockets to suit applications where continuous oil supply is impractical or grease application is difficult.
Material Structure
- Sinter bronze liner material: CuPb6Sn6Zn3
- Metal backing: Low carbon steel back
Surface Configurations
Product Availability
- Standard cylindrical bimetal bushings, bimetal thrust washers, and bimetal strips
- Custom designed bimetal bearings produced with short lead times
Applications
PVB036 bimetal bearings are suitable for medium speed and medium load applications with oil lubrication. Bimetal bushes with surface-coated soft alloy can serve as bearings and connecting rod bushings for high-speed internal combustion engines.
