NORGLIDE® MP Bearings
A plastic material which allows the large-scale production of bearings.
NORGLIDE® MP is a maintenance-free bearing material with a woven metal fabric encapsulated in a wear-resistant PTFE compound which offers high-load capabilities. This combination of materials enables easy manual or automatic processing and installation.
NORGLIDE® MP can be adapted to many applications, including severe chemical environments. The material allows excellent sizing so that an interference fit of the bearing to the shaft can be designed to produce particular torques or eliminate play.
This metal fabric is available in either tin, bronze or stainless steel. The standard PTFE compound contains glass fibers and graphite. Special PTFE compounds are available on request. Fabricated parts include die-cuts, rolled cylinders, flanged cylinders and deep-drawn bearings. NORGLIDE® MP can be prepared for bonding (etched one side). It can be supported or backed with steel or plastics.
