Steel Back PTFE Lined Bushing DU Bearing

PVB010 Steel Back PTFE Coated Metal Polymer Composite Plain Bearing

PVB010 metal polymer self lubricating plain bushing is made of low carbon steel back with sintered bronze powder and PTFE mixture. This type of composite plain bearing is also called coated self lubricating bearing,DU bushing,Metal Polymer plain bearing,PTFE lined dry sliding bearing,SF-1 oilless bearing,LFB oil free bushes and etc. 

• 1. PTFE/Pb mixture 0.01~0.03mm as sliding layer, provides an excellent initial transfer film, which effectively coats the mating surface of the bearing assembly, forming homogeneous oxide type solid lubricant film.
• 2. Porous bronze 0.2~0.3mm, provides Max. thermal conductivity away from the bearing surface, also serves as a reservoir for the PTFE-lead mixture.
• 3. Low-carbon steel backing 0.7~2.3mm, provides fundamental structural support and gives exceptionally high load carrying capacity, excellent heat dissipation.
• 4. Tin-plating 0.005mm or copper plating 0.008mm, provides good corrosion resistance.

• Good wear and friction performance over a wide range of loads, speeds and temperature without oil
• Also perform well with lubrication
• Maintenance-free, long life
