QD bushed sheaves (a-b-section) 5-groove have five grooves on the sheaves. They use well designed and installed V-belts that can be operated in speeds ranging from 5 to 30 m per second. This ensures high functioning capability, a quiet, smooth, and little maintenance system. V-ribbed sheaves with smaller belts and groove sections operate with much less noise than other types of grooved sheaves. They have V-belts that have tapered sides and fit into corresponding pulleys with side guides. V-shape allows the belt to fit perfectly into the groove to prevent the belt from turning over or side drifting. V-belts
wedge into the groove when the load increases; hence, heavier loads increase the wedging to improve power transmission. The material used to make the QD bushed sheaves
largely depends on the manufacturer or brand. The QD bushing sheaves can be made from steel or cast iron. Sheave machines that are made of steel are much more resistant to impact. The Sheaves starts to show signs of wearing out if their grooves deepen or get rounder. MRO Supply has a wide assortment of bushed sheaves in various styles and sizes.
