Torque Limiters

The torque limiter is a protective device that limits torque transmitted in a drive system by slipping when a preset value is exceeded as a result of shock load, overload or machine jam. It automatically re-engages when the overload is removed, no setting being required. Torque is transmitted by spring loaded friction faces, the value being preset by adjustment of the spring force by simple setting of the adjustment of the nuts and bolts.

Torque Limiters

The original series torque limiters and spares based on Imperial dimensions and a new range of metric torque limiters providing both smaller and larger units. Both series are available with a roller chain coupling.

Available in eleven standard sizes, they are easy assembly units providing protection and reliability.

Sheargard Clutches and Couplings

The Sheargard clutch uses shearpin wedges to provide total disengagement of driving and driven members in the event of an overload, it is suitable for high torques with a compact, low inertia unit. Available as a roller chain coupling and rubber elastic couplings.
