Product Description

Self-lubricating PTFE Composite Du-B Bronze bushings material to manufactuer your bushings.

Tell us about your application

 

composite bushing material strips or sheets. . PTFE-lead overlay

 

The composite bushing is the higher performance self-lubricating bearing material available anywhere. It offers a combination of properties and capabilities unmatched by any other self-lubricating bearing material and, consequently, has the broadest application range

 

Composite 3 layer bushing bearings combine the advantages of many conventionally lubricated, metallic plain bearings—particularly high load capacity and dimensional rigidity—with the design freedoms of self-lubricating materials, including the ability to operate successfully well beyond the scope of conventional lubricants.

The high-performance self-lubricating bearing bushing material

1. Bronze Backing
This bronze backing gives bushing its exceptionally high load carrying capacity; thin, compact design; excellent heat dissipation; and dimensional and structural rigidity.
 
2. Porous bronze inner structure This comprises a nominal 0.010 inch (0.25 mm) thick layer of carefully sized bearing quality bronze powder which is sintered onto the steel backing. This porous structure is impregnated with a homogeneous mixture of PTFE (polytetrafluoroethylene) and lead. In addition to providing maximum thermal conductivity away from the bearing surface, this unique bronze inner structure also serves as a reservoir for the PTFE-lead mixture
 

The Material shall consist of 3 layers, a bronze backing strip, and a sintered interlocking porous matrix, impregnated and overlaid with PTFE / lead mixture

Sintered Bronze PTFE Composite Material - maintenance-free

This low friction overlay, approximately 0.001 inch (0.025 mm) thick, provides an excellent initial transfer film which effectively coats the mating surface of the bearing assembly, forming an oxide type solid lubricant film. As this film is depleted, the relative motion of the mating surface continues to draw material from the porous bronze layer. When conditions are severe, the feed of lubrication is increased. The peaks of porous bronze coming in contact with the mating surface generate localized heat and, due to the high thermal expansion rate of the PTFE, force additional lubricant to the bearing surface. The relative motion of the mating parts wipes the lubricant over the interface, continuously restoring the low friction surface fill
