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.


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.
