metal polymer bushing
PTFE-lined metal-polymer bushing: PVB010 (DU),PVB011(DUB)
Our metal-backed, PTFE-based (polytetrafluoroethylene) polymer bearing materials have a common structure, consisting of a steel backing bonded to a porous bronze sinter layer. This bronze sinter layer is impregnated and overlaid with the filled PTFE bearing lining.
The steel backing provides mechanical strength, while the bronze sinter layer provides a strong mechanical bond between the backing and the bearing lining. This construction promotes dimensional stability and improves thermal conductivity.
These polymer bearing linings, being predominantly PTFE, offer exceptionally low friction.
Thermoplastic-based metal-polymer Bearing; PVB020 series (DX)
DX Bearing have a similar structure to the PTFE-based materials (DU bushing) described above; but with these products, the bearing lining consists of a filled thermoplastic extruded tape (POM).
These materials are generally designed to operate with marginal lubrication. DX bearing are most commonly provided with a uniform pattern of indents in the bearing surface that act as grease reservoirs.
