Variable Speed Sheaves

Speed adjustments are part of the pulley’s design benefits. The secret is within the threaded, angular faced discs that are the core of the V-shaped groove on each pulley. If you need more speed, move the discs toward each other. This alignment produces a belt that simply rides higher in the groove. Achieve a larger pitch diameter than before with this adjustment. Meet every requirement in your industry by slowing the machinery down to a specific rate. Simply increase the space between the two discs, which slows down the belt’s motion.
