SA Series Ratchet Torque Limiter for PTO Shaft
A ratchet torque limiter is a device that interrupts power transmission in the event of a torque spike or overload exceeding the setting. After removing the cause of the overload, the torque limiter will automatically re-engage. Ratchet torque limiters are typically used to protect appliances subjected to constant or alternating torque from overloads.
