Pulleys Fields of Use
Variable speed pulleys are intended for transmissions with a change in speed, in which the transmission is realized by a variator or V-belt.
Typical use is in the repair of older agricultural machinery or conveyors in the ceramic and woodworking industries, or simply in machines where the speed change is mechanically controlled, especially in presses, single-purpose machines and other applications.
Nowadays, they are very often replaced by another solution for setting the required revolutions.
