In applications where the rollers are exposed to solvents or chemicals, the rubber covering of the sides of the core and of the shafts, may increasing the lifetime of the rollers.
We cover the sides and a part of the shafts with the same or another rubber as the roller is covered with.
This additional cover seals and protects the metal parts from corrosion.
