Müller Martini 3011.2748.4 Free-wheel

The free-wheel, also known as an overrunning clutch, sprag clutch, or indexing clutch, with type number 3011.2748.4 from Müller Martini, is a mechanical coupling for transmitting torque in only one direction of rotation. It has the dimensions 6 x 6 x 2 cm and weighs 0.23 kg. Free-wheels allow rotational movement in one direction and block rotation in the opposite direction, thus serving as important components in drive technology to ensure overrunning of a drive or to prevent back-rotation. Typical applications include printing machines for precise paper guiding and conveyor systems to prevent rollback, as well as packaging machines for synchronized component movement.
