Description
Variable Pitch 1VP50 Pulley 3/4″ is designed and engineered in a way that allows for precise adjustments in diameter, which will also correlate to speed adjustment. Our single-groove variable pitch pulleys are manufactured with extremely tight thread tolerances and use a high-quality cast iron material. They are extremely well balanced to reduce vibrations and are phosphated and painted for corrosion resistance. Besides 1VP50 pulleys with a 3/4″ bore we also stock a full line of high-quality performance 3L, A, 4L, and AX v-belts as well as a full line of industrial power transmission components.
