271P.25.28.F

The 271P.25.28.F is an Adjustable Rotary Friction Clutch can be fully mounted or adapted for inline coupler use with coupler adaptor. The construction is simple and robust, comprising a series of steel clutch plates engaging a hub plus a series of friction rings engaging a housing. Pressure is brought to bear on the plates and friction rings by an adjuster acting through a spring and pressure plate. Controlled slip takes place between the hub and housing whenever the load exceeds the set torque. As a torque limiter, Vari-Tork interrupts continuity between power source and load when this 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. The load can be connected to either the steel inner hub or the aluminium alloy housing.
