1.PTFE with lead 0.01~0.03mm as sliding layer
2.Porous bronze 0.2~0.3mm
3.Steel backing 0.7~2.3mm
4.Tin-plating 0.005mm or copper plating 0.008mm
New type material which is designed on the basic of PVB010 oiless bearing
Low friction under oil lubricated condition.
Wear resistant and anti-impact.
Particularly applied for the high PV condition, at hydrodynamic lubrication, similar performance with DP4 bushing
· Standard cylindrical bushing, thrust washers and strips are available.
· Special designs are produced at short time
· Lead free bushing is also available
PVB013 self-lubricating bushing is the best choice for all kinds of gear pumps plunger pumps, vane pumps and so on.
