trasmissioni industriali oil/air supply 12 bar in-line and side load application The HFR clutches have been designed to complete the TRANSFLUID range of power take offs for new potential markets. The oil-air actuation is provided by oil or air radial inlet instead of axial as the HFO: this configuration permits the mounting of couplings and/or cardan shafts on the output shaft. The actuation oil or air is controlled externally and enters the clutch radially directly into the bearing carrier. Pressure switch Oil power pack for HFO Control and management of the HFO-HFR equipment: By customer...
