Rulon® materials are used extensively inside machinery as bushings, washers and piston rings, replacing expensive metal roller bearings or multi-component linear guide rings. Our materials exhibit good chemical compatibility, including good wear properties and performs well both in low friction and low thermal expansion conditions.
The piston ring can be designed and manufactured into special shapes to accommodate typical dimensional tolerances.
