Product Profile of Metal - Polymer Materials
GGB Bearing Technology is the largest manufacturer of metal-polymer plain bearings.
The metal-backed, PTFE-based [polytetrafluoroethylene] polymer bearing materials have a common structure, consisting of steel backing bonded to a porous bronze sinter layer. This bronze sinter layer is impregnated and overlaid with the filled PTFE bearing lining.
Thermoplastic-based metal-polymer materials, the bearing lining consists of a filled thermoplastic extruded tape. These materials are generally designed to operate with marginal lubrication. The incorporation of PTFE filler in DS enables this material to operate dry when required. Due to the inherent lower friction of this polymer blend, it is usually supplied without indents.
