Description Delivery Returns
Machinable steel backed, acetal co-polymer lined, composite bearing material designed for marginally lubricated operation that is particularly suitable where continuous oil lubrication is uneconomic or inappropriate. The bearing surface may be supplied indented for grease lubrication or it may be plain for applications where fluid lubrication is available. The indented material surface which should be filled with suitable grease during assembly is designed to provide optimum distribution of the lubricant over the bearing surface. Dependent on conditions, these bushes can withstand temperatures from -40 degrees up to 130 degrees for short periods and specific loads up to 140N/mm2.

Wrapped Acetal Lined Plain bearings consist of a composite material in which porous bronze layer is bonded to a metal backing and impregnated and lined with a polymer surface. It is the choice of this polymer which imparts to each material its particular bearing properties.
