CuSn10Pb10 Bimetal Bushing Composite Copper Alloy Metallic Bushing

ZR-031 bimetal bearing is made high quality low carbon steel as backing, sintered bronze alloy which with low friction properties as the wear-resistant layer.Composite bimetal bearing inner bronze alloy surface can be processed with various types of oil grooves, oil hole and oil pockets according to the different working applications. PVB031 bimetal bush is suitable for the conditions which can not continuously put oils or difficult to apply the grease. It's also called JF-800 Bi-Metal Bushing,SY bimetal plain bearing, Steel back SAE792 bimetallic bushings.

1.Sinter bronze with graphite-- Liner material: CuPb10Sn10 .Good wear resistance with lower friction and excellent load carrying capacity. Bimetallic bushing can be machined after fitting to get precision tolerance. We also can supply the bearings with PTFE or graphite sprayed layer on the work surface to get much lower start friction.
2. Metal backing --low carbon steel: gives exceptionally high load carrying capacity, excellent heat dissipation.

Inner Surface Oil Pockets Types

Bimetal Bush Oil Grooves types

Bimetal Bushing Gap Types

1. Standard cylindrical bimetal bushing, flanged bimetal bearing, thrust washers and strips are available.
2. Special designed bimetal bearings are produced at short notice

The special structure of this type self-lubricating bearing is suitable for hostile environments, for high load application which lubrication is difficult. Now ZR-031 bimetallic bush has been widely used in water turbines, vane controls, injection molding machinery, packing machines, construction equipment, tire moulds, paper production machinery, furnace expansion plates, automotive transmission, heavy lifting chain linkage, food production equipment etc.
