Variable speed pulleys and motor slide bases

Home › Products › Variable speed pulleys and motor slide bases

Expandable-disc pulleys (divided into two main families) represent the simplest and most cost-effective solution for rapidly and continuously changing the rotation speed of two shafts without stopping the transmission.

  • High reliability;
  • Wide product selection;
  • Easy installation;
  • High-precision manufacturing;
  • Competitive pricing without compromising quality;
  • “Made in Italy” certified quality.
  • Variable Center Distance: Consists of two discs sliding symmetrically on a hub. It transmits motion to a “fixed” driven pulley with speed ratios up to 1:3.5, achieved by varying the distance between the centers of the two pulleys.;
  • Fixed Center Distance: Consists of a pair of pulleys, both featuring a single movable disc. This allows for speed variation with a ratio of up to 1:12.3, adjusted via a handwheel on the driving pulley..
