SIT Poly-V pulleys have a statically balanced degree of G6,3 at 1500 rpm in accordance with ISO 1940. On request it is possible to perform static balancing at higher de - grees or dynamic balancing. ˇ %)˚ Due to a constant improvement of our products, technical data of the pulleys may be subject to changes.

Correct accurate installation of V-Belt Pulleys is essenial to provide long life of the belts. Pulley alignment and parallelism are very important as any misalignment of the pulleys will cause unequal loading in the belt and cause edge we the belt. Pulley alignment can be checked by placing a straight edge across the outside edge of the

Typically, v-belt drives operate between 1,500 to 6,000 ft/min, with 4,500 ft/min the ideal capacity for standard belts. Some narrow v-belts can operate at speeds of up to 10,000 ft/min, but these pulleys must be dynamically stabilized.
