Air Cooled Drum Clutches / Brakes

The Pneuflex units are designed and built for severe clutching and braking applications on heavy duty equipment. They are unmatched for high stating loads and sustained slippage where heat generated tends to shorten the operating life of conventional clutches. Their high torque ratings permit use of small diameter compact units. Ventilated construction permits passage of cooling air to rapidly dissipate heat from the friction shoes. Torque is transmitted from the side plates of the elements through torque bars to the friction shoes. Pressurizing the actuating tube forces the friction shoes to engage around a cylindrical drum. Leaf springs in the torque bar cavities of the backing plates retract the friction shoes when the actuating tube pressure is released.
