The Centric VOR is a pneumatic clutch that provides unmatched dependability for thousands of torque overloads. This bi-directional clutch limits the transmitted torque based on the air-pressure supplied. Pneumatic clutches offer In-Flight torque adjustability without shutting down the equipment to adjust the clutch torque. Reliability is crucial for paper processing equipment that runs continuously and the VOR clutch delivers that dependable torque control. Pneumatic clutches provide more accurate torque control (+-5%) and offer more flexibility than mechanical torque limiters.
