DU Metal-Polymer Composite Bushing International Bearings

DU bushing is a standard item of our company 

DU bearing is also called Teflon bushing, SF-1 oilless bearing, PTFE lined bearing, plain dry bushes, DU bush. 

Product Feature 
Structure: Bronze Backing + Bronze Sintere + PTFE/Pb 

1. PTFE/Pb mixture 0.01-0.03mm, provides an excellent initial transfer film, which effectively coats the mating surface of the bearing assembly, forming an oxide type solid lubricant film. 

2. Sintered bronze powder 0.20-0.35mm, provides max. Thermal conductivity away from the bearing surface, also serves as a reservoir for the PTFE-lead mixture. 

3. Bronze backing, gives exceptionally high load carrying capacity, excellent heat dissipation. Have very good corrosion resistance. 

Suitable for dry running, low coefficient of friction, lower wear, good sliding characteristics, forming a transfer film can protect the mating metal surface, suitable for rotary and oscillating movement. Very high chemical resistance, low absorption of water and swelling. Also performs well with lubrication. Bronze backing provides improved corrosion resistance
