Multiple-disc clutch HFO - HFR

TRANSFLUID has developed the HFO-HFR clutches to meet the growing market demand for power take-offs for high speed, high horsepower industrial engines, and remote-control operation. HFO consists of an oil actuated clutch assembly (dry plates) with shaft and bearings suitable for high radial loads mounted in a cast iron housing that provides easy engine installation. The connecting flange and housing to the engine are SAE standard. A rotating union provides the oil actuation mounted on the shaft end allowing the oil to engage and disengage the clutch. This system allows the use of HFO clutches for belt-driven applications only. The oil actuation allows remote control as well as a larger transmittable torque compared to the traditional over-center PTOs. Due to the continuous pressure applied to the clutch plates, the HFO is a self-adjusting clutch that drastically reduces maintenance costs, especially on heavy-duty applications where plate wear is typical. The HFR clutches have identical performances as HFO but it is designed for in-line applications. The oil actuation is provided by radial oil inlet in the bearing carrier allowing the same operation as HFO clutches.
