DU & DUB Type Dry Self Lubricating Bush & Bearings Oil Less/ Olite. It consists of Three layers:
1. PTFE
2. Bronze
3. Steel

DU and DUB Type Dry Bush & Bearings  (Oil Free) take advantage ofthe outstanding dry bearing properties of Polytetrafluoroethylene(PTFE) and combines them with strength, stability and good wearresistance, excellent heat conductivity and low thermal expansion. 


DU consists of three bonded layers: 
a steel backing strip and a porous bronze matrix, impregnated and overlaid with the PTFE/ lead bearing material.

1. PTFE           0.01~0.03mm
2. Porous bronze 0.2~0.3 mm
3. Steel /Bronze backing 0.7~2.3 mm
4. Tin-plating  0.005 mm or copper plating 0.008mm

DUB also consists of three layers: 

Bronzebacking replacing the steel backing strip. The structure is otherwisethe same as that of DU. The bronze backing provides a high corrosionresistance, anti magnetic properties and a good thermal conductivity.
