The load can either be connected to the steel inner hub or the aluminium alloy housing. Features and Benefits. Compact proportions 4 interface styles Set screw or clamp connection Can be used as a torque limiter, tensioning, overrun device. Product Application Information. As a torque limiter, Vari-Tork interrupts continuity between the power source and load when it reaches a pre-determined level. As a tensioning device, Vari-Tork typically maintains tension in a filament or tape winding operation by exerting drag on the feed spool. As an overrun device, Vari-Tork absorbs residual inertia of a motor when the load is braked or reaches a terminal stop.
