The Power Grip PO Clutch is a pneumatic clutch suitable for inline or shaft-to-shaft applications. This design utilizes a large diaphragm that compensates for wear during the life of the friction material with no adjustment necessary. Standard Quick Release Valves ensure swift disengagements. The manual mechanical lockup feature allows clutch engagement in the event of air system failure. WPT®'s Power Grip PO Clutch is available in 1, 2, or 3 plate construction with diameters ranging from 14" thru 42".
