Torque Limiters

The Hercus Torque Limiter is an adjustable friction drive when set prevents over loading, when the preset load is reached the limiter will slip dis-engaging the drive.  The moment the load falls below the preset, the limiter will re-engage and will resume driving.

The selected driving plate* (i.e. Sprocket, Gear etc.) is mounted on a self lubricating bush that is carried on the hub and held between two friction disks.  The load desired is applied to the pressure plate by the Disc spring or springs.

*Please Note (Driving Plates are options - not supplied with standard Torque Limiter - Hercus can supply and fit at time of order at addtional cost.)
