Composites bearings are used in a wide range of industries for their strength, superior wear and friction characteristics, and their ability to operate without external lubrication. Filament wound composite bearings with the most effective tribological performance have historically been limited in their dimensional tolerance by the processing capabilities inherent to the winding process ...

Metal-polymer bearings have been relatively successful in replacing traditional leaded bronze or bi-metal bearings in many lubricated applications. Until recently however, PTFE based metal-polymer plain bearings were unable to match ...
Polymer bearings with a PTFE-based running surface were first introduced as a breakthrough in scroll compressor performance approximately 30 years ago. These bearings consisted of the polymer surface, porous bronze interlayer and steel supporting layer...
Traditional compressor bearings, such as rolling element, leaded-bronze or bi-metal bushings, are greatly affected by wear in marginally lubricated conditions at bearing locations in compressor applications. Metal-polymers offer a unique advantage...
