Ondrives.US mechanical clutches are rotary friction clutches with adjustable or fixed drag or slip torque. Whenever the load exceeds the set torque, controlled slip takes place between the hub and housing.  These slip clutches can be supplied for shaft to shaft applications or for shaft to component drives

Mechanical clutches can be used as:

Torque limiter slip clutch  -  interrupts continuity between power source and load when this reaches a pre-determined level.

Tensioning device or Drag brake  -  maintains tension in a filament or tape winding operation by exerting drag on the feed spool.

Overrun device  -  absorbs residual inertia of a motor when the load is braked or reaches a terminal stop. Good for soft starts, cushioned stops and overload protection.

Overload protection  -  clutch slips when mechanism is jammed. This protects the operator and machinery. 

Torque control  -  drive screws, bottle caps etc to a fixed torque setting.

Indexing  -  motor runs continuously while the clutch slips until the next index.

Hinge position  -  hold a hinged door or lid at any position, fingertip reposition.
