Hydraulic special self lubricating bearing

PVB013 self-lubricating bearing 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 oil free bushes,plain sliding bearing, teflon bushes,PTFE coated bushings and pump bearing.

Material structure:

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

Characteristics:

• 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

Availability:

• Standard cylindrical bushing, thrust washers and strips are available.
• Special designs are produced at short time
• Lead free bushing is also available

Applications:

PVB013 self-lubricating bushing is the best choice for all kinds of gear pumps plunger pumps, vane pumps and so on.
