PVB013 hydraulic gear pump DU bushing is a kind of DU bushing special designed for pumps. Hydraulic self lubricating bearing has common structure with other DU bush. It's also called gear pumps DU bushing, SF-1T Sliding Bearing.
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.
