The centrifugal clutch with pulley, like the centrifugal clutch with automatic belt tensioners, offers the benefit of a compact build in which an additional tensioning roller is not needed in the belt drive.
In the centrifugal clutch with adjustment disc, the drum is formed as a regulating hub. The regulating hub adjusts the belt pre-tension. The regulating nut is secured with grub screws in the adjustment area and can be set smoothly. These centrifugal clutches are also used in shaker plates.
