bimetal bushing is based on steel and sintered with CuPb10Sn10 as a lining layer. This type has the best performance within the range of Cu-Pb alloy constructured bushing. Therefore it has been widely used in automotive, common industrial like steering gear, power steering, pedal bushes, king-pin bushes, tailgate pivots, mechanical handling, lifting equipment, hydraulic motors, agricultural machines etc.
Metal backed with bronze graphite oilless bearings
1. Sinter bronze powder with graphite: good wear resistance with lower friction and excellent load carrying capacity. It can be machined after fitting to get precision tolerance. PVB also can supply the bearings with PTFE or graphite sprayed layer on the work surface to get much lower start friction.
2. Metal backing: gives exceptionally high load carrying capacity, excellent heat dissipation.
3. Copper plating 0.002mm, good corrosion resistance.
The standard bearings we supply as plain surface, also we supply with cleaning grooves for small angular movements or in the presence of abrasive media or dirt, and indented surface for grease lubricated applications.
