Smallest in-line slip clutch with zero
backlash

Believed by its maker Huco to be the smallest of its kind available, the new Vari-Tork miniature in-line slip clutch is 16mm in diameter and 26mm in length.

Believed by its maker Huco to be the smallest of its kind available, the new Vari-Tork miniature in-line slip clutch is 16mm in diameter and 26mm in length Its torque range is 0.1Ncm to 0.5Ncm, with a claimed zero backlash

The construction of the Vari-Tork is said to be simple, robust and comprises a series of steel clutch plates engaging a hub and series of friction rings engaging a housing.

Pressure is brought to bear on plates and rings by an adjuster acting through a spring and pressure plate.

Drag or slip torque is adjusted by means of a single screw accessible through the Vari-Tork's nylon housing.

This rotary friction device is supplied with 4mm bores as standard.

In common with other models in the Vari-Tork range, the miniature version can be used as a torque limiter, whereby it interrupts continuity between power source and load or as a tensioning device, typically maintaining the tension in a filament or tape winding operation by exerting drag on the feed spool.

As an over-run device, it absorbs residual inertia of a motor when the load is braked or reaches a terminal stop. Request a free brochure from Huco Dynatork ...
