Used for torque loading and power absorption in test benches, actuators, etc, as well as tension control with wire, cable, ropes, threads, paper and foils at take-up and payoff equipment.Can be used as start coupling for rpm speed up control and as overload protection or braking against backlash. These brakes are noiseless, frictionless and wear free in their operation.Torque is independent from rpm speed. Torque is infinitely adjustable within each brake’s range of operation.
