SA series Ratchet Torque Limiter

SA series Ratchet Torque Limiter

A ratchet torque limiter is a device able to interrupt the transmission of power in the event of a torque peak or overload that exceeds the setting. The torque limiter is automatically re-engaged after the cause of the overload is removed. Ratchet torque limiters for PTO shaft are generally employed to protect implements subject to constant or alternating torques from overloads.

PTO Shafts & Agricultural gearboxes are Available

A PTO shaft is a highly sophisticated mechanism that allows implements to draw energy from an engine. It works with a mechanical agricultural gearbox. A PTO shaft can be mounted on a vehicle's transmission, and is an essential part of the system. A high-quality PTO shaft should be durable enough to withstand torsion and minimize vibration.The agricultural PTO gearbox is designed to change the output speed of a PTO drive shaft. It can be used as a decreasing or increasing ratio gearbox. With the decreased ratio gearbox, it reduces the PTO shaft's speed from 1000 rpm to 540 rpm, allowing you to use equipment designed for 540 rpm. On the other hand, an increasing ratio gearbox increases the speed of the PTO shaft from 540 rpm to 1000 rpm.Raydafon manufactures a wide range of durable PTO shafts and agricultural gearboxes to meet all your requirements.
