NORGLIDE® PRO Bearings
Its complex composition--steel plate, structured bronze layer with encapsulated PTFE sliding layer -- its load-bearing capability is almost twice as much as other NORGLIDE® Bearings.
NORGLIDE® PRO is a steel material with a polygon-structured bronze layer on one side. Encapsulated in the polygon structure is a sliding layer of compounded PTFE tape. This design provides much higher load-carrying capabilities.
The material is capable for sizing and can be adapted to any clearance required for the specific application. The whole range of NORGLIDE® PRO thicknesses can be designed with a press fit in the housing.
PTFE compounds are available with carbon or EKONOL®. Fabricated parts include rolled bearings with or without an axial flange, deep-drawn bearings and die-cuts.
