ARIA-OLIO are automatic axial chain or belt tighteners that use either the thrust of compressed air (ARIA) or that of oil (OLIO). ARIA is an elastic tightener as the air, due to its physical properties, is compressible, whereas OLIO develops a constant and continuous force. The two models can be used both in thrust and in drag conditions and can be equipped with many different interface kits: polyethylene sliding blocks, polyethylene wheels on fork, pinions on fork and zinc plated steel rollers on fork. ARIA-OLIO are the only tighteners in the world that can work with a constant or changeable load, independently of the remaining stroke, depending on the alimentation circuits, for the entire working time of the chain or belt that has to be kept in stretch.
