The 5-groove QD bushed sheaves are made from cast iron. Once fitted, they can attain a maximum speed of 6500 FPM. The sheaves are balanced to precision, which is a standard requirement for similar products with speeds of 5000 FPM and beyond. Also, static balancing is necessary to enable the sheaves to withstand mechanical vibration.These QD sheaves are compatible with belt types A to C. The product’s outside diameter ranges from 3.75 inches to 71 inches, while the pitch diameter is almost the same. Regarding the bushing type, the QD bushed sheaves D-section
(5-groove) fit with SK, SF, E, F, and J bushes.The smaller QD sheaves, i.e., the ones with an outside diameter of 3.75 inches, are common in the oil industry equipment. Reverse mounting is possible with these sheaves. You can insert the bolts
first through the sheave before entering it into the bushing or the other way around.Get the best selection of QD sheaves in various sizes, styles and grooves. MRO Supply stocks a wide assortment of sheaves to suit light and heavy duty applications.
