PVB031 Steel Back CuSn10Pb10 Copper Alloy Bimetal Bushing
PVB031 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.
Material Structure
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
Availability
1. Standard cylindrical bimetal bushing, flanged bimetal bearing,
thrust washers and strips are available.
2. Special designed bimetal bearings are produced at short notice

Application
The special structure of this type self-lubricating bearing is
suitable for hostile environments, for high load application which
lubrication is difficult. Now PVB031 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.
