Designed for harsh, washdown environments, the clutches and brakes feature all stainless steel construction and require no electricity to operate. Since torque is independent of slip speed, smooth torque is achieved as low as 1 RPM up to 1800 RPM. Smooth slip torque provides constant torque for tension or torque limiting applications. Units provide dependable performance, with no friction surfaces to break down or wear out. They also feature 400 Series stainless steel bearings designed for long life.
