PVB035 Friction-Welded Track Roller Bimetal Bushings
PVB035 friction welding bimetal bearing is made of bimetal rolling bearing and bimetal thrust washer by welding. This type of bimetal bush adopts copper alloy at the sliding part in contact with the shaft, which can provide good lubrication and protection to the shaft during use. The steel back has stronger bearing capacity and further reduces material costs.It is also called Flanged bimetal bush
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.
Characteristics
Application
PVB035 Track roller bimetal bushing is widely used for construction machinery, such as track roller, carrier roller, idler of bulldozers, excavators and wheel loader
