■ Technical Data

Bimetal-bearing is a bimetal bearing, wrapped of steel sheets with a layer of lead bronze.

· Bronze layer: CuPb10Sn10
· Load Capacity: 150N/mm2
· Max. Speed: 5m/s
· Hardness: HB 60~90
· Product description: WF-BM Flange Bimetal Bearing Bushing,flange bimetal bearing,bimetal bushing,bimetal bush

The standard sizes are fitted with lubrication indents on the running surface. For standard bearings is normally the steel backing copper plated to improve the corrosion resistance. The layer of lead bronze makes it possible to use these bearings with relative long lubrication intervals.
Bimetal-bearings can be manufactured with a thicker lead bronze layer for applications where the bearing has to be machined after mounting. The material of the layer can be fitted to the special needs for the application in question.
