Mach III friction torque limiters, also known as slip clutches, are designed to transmit a fixed amount of torque from one machine component to another until an overload is experienced. When that torque is exceeded, the friction torque limiter slips until the overload ceases. Torque setting is established by compressing the adjustment nut to the desired torque output, then fixing it in place with the provided set screw(s).
IMPORTANT: Mach III friction torque limiters do not disengage upon overload. A means of sensing and stopping the overload condition must be in place or a friction torque limiter will continue to slip, eventually overheating to the point where it is unfit for continued use.
