PVB030G Steel Back Bronze Alloy Graphite Filled Bimetal Bushing

PVB030G Graphite filled steel copper bimetal bushing is made of low carbon steel, Sintered bronze alloy CuSn10Pb10 and graphite filled oil pockets. Oil pocket graphited bimetal bushing use lead tin bronze as inner layer and add the special graphite lubricant with a fine tough steel material as outer layer. With minimum 25% graphite lubricant to inset into oil pockets along with its oil groove distributed structure, therefore, it can enhance its self-lubricant performance.

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.

Bimetal Bushing Gap Types

• Standard cylindrical bimetal bushing,thrust washers and strips are available.
• Special designed bimetal bearings are produced at short notice

Characteristics

• Suitable to use on the difficult place of oil supplying and can be used without oil
• Bearable high loading capability and can enhance its high performance during mid-speed revolution
• Anti-corrosion function
• High precision through grinding
