Bronze Back PTFE Composite Bushing Sintered

PVB011 Bronze Back PTFE Lined Self-Lubricating Composite Plain Bushing

PVB011 PTFE lined self-lubricating DU-B bronze bearing is made of bronze back with sintered bronze powder and PTFE layer. This type of sliding bearing is also called DU-B Bushing, PAP P11 composite plain bearing,bronze back coated self-lubricating bushing,oil free bronze bushes,SF-1B oiless bearing,plain dry sliding bronze bearings. 

1.PTFE with Pb 0.01~0.03mm

2.Porous bronze 0.2~0.3mm

3.Bronze backing 0.7~2.3mm

• Good wear and friction performance over a wide range of load, speed and temperature conditions without lubrication.
• Also can perform well with lubrication.
• Bronze backing provides improved corrosion resistance compared with PVB010 self lubricating steel back bushing.
