Oilless Self Lubricating Bearings Wrapped By Steel Backing Sinter Bronze Layer And PTFE Antiwar Surface
DU Bushing is wrapped by steel backing, Sinter bronze layer and PTFE antiwar surface.
Structure:
1. PTFE with Pb 0.01~0.03mm
2. Porous bronze 0.2~0.3mm
3. Bronze backing 0.7~2.3mm
Characteristics:
DU bushing(PVB011) has good wear and friction performance over a wide range of load, speed and temperature conditions without lubrication
This self-lubricating bearing also can perform well with lubrication
Bronze backing provides improved corrosion resistance compared with PVB010 ollies bearing
Availability:
Standard cylindrical bush, flanged bushing, thrust washers and strips are available.
Following sizes are standard
0606DU,0808DU,1010DU,1210DU,1415DU,1515DU,1615DU,1815DU,2020DU,2220DU, 2525DU,2825DU,3030DU,3530DU,3840DU,4030DU,4040DU,4530DU,5040DU,5550DU, 6050DU,6550DU,7060DU,7560DU,8050DU,8560DU,9060DU,9560DU,10080DU
Special designs can be made according to your requirement
Lead free type is also available
Applications:
Plain dry bushing (PVB011) is widely used in steel metallurgy industry, cement grouting pumps and scrow conveyers of machine, marine and offshore equipment, dyeing machinery and so on
