NORGLIDE® SM Bearings
Material maintains sizing capability to a large extent with the capability of higher loads.
NORGLIDE® SM is a composite material of compounded PTFE, bronze stretched metal and steel backing. This material structure combines the bearing characteristics of PTFE compound tape with the sizing capabilities of stretched metal.
These bearings can also be designed without play. Bearings of 1 mm of wall thickness or greater can be produced with an interference fit in the housing. Various methods are available to protect the steel shell from corrosion.
Availability
The standard PTFE compound contains carbon and graphite. Special PTFE compounds are available on request. Fabricated parts include rolled bearing with or without an axial flange, deep-drawn bearing and die-cuts.
