The Morse M Series Torque Limiters and Couplings are a Friction type of overload protection and are of general use and very low cost.

The Morse Torque Limiter is a protective device that LIMITS TORQUE transmitted in a drive system by slipping when the torque demand exceeds a preset value as a result of shock loads, overloads, or machine jams. It automatically re-engages when the overload torque has passed; no re-setting is required. It prevents machine damage and eliminates costly breakdown time.

The Torque Limiter utilises spring loaded friction surfaces for its operation; slip torque is preset by adjustment of the spring force. The Torque Limiter can be used with a sprocket, gear, sheave or flange as the centre member clamped between two friction facings. Offered complete with a range of specially machined platewheels and shaft to shaft couplings, with torque range 3 - 8540 Nm.
