WPT® Low Inertia (LI) High Torque Clutches provide the highest torque-to-size ratio of any WPT® Low Inertia product. WPT®'s LI High Torque features a "pancake" airtube which provides maximum actuator contact area increasing the clutch torque capacity. A large air connection is mounted directly to the airtube allowing for rapid clutch response time. WPT®’s Low Inertia High Torque Clutches are available in 1, 2 or 3 plate configurations with diameters ranging from 11 through 36 inches.
