Fitting in workshop or directly on system quick and easy installation without cylinder preparation, without screws thanks to already calendared rubber bars (hardness 70 Shore +-5) Non fiammable type FLAME STOP GRM2311 – original process with transverse grooves of 12 mm thickness moulded on a Corten steel backing plate of 2 mm. Increase of friction coefficient between the belt and the cylinder and therefore: no slipping or heating. Load being equal, a lower tension is required and the belt thus suffers less stress. Surfaces with special cuts for: self-cleaning of the cylinder and constant tension even in the presence of water.
