Description: 7Groove QD groove bushed sheaves are pulleys with seven grooves on the sheave surface that only use 3V section types of belts. The purpose of the grooves in the sheaves is to prevent the slipping of the V belts when the drive belt is running, which improves power transmission and belt drive speed. The efficiency of the drive belt is crucial to the speed, moment of force, and the transmission power in the pulley system. 7Groove (QD-bushed-sheaves/3v-section/7groove/) that are made of steel sheaves have higher impact resistant compared to their capability for handling heavy loads. The system runs quietly and smoothly compared to other pulleys systems that have chains or belts with flat cross-sections. The sheaves’ high number of grooves further reduces the chances of the belts slipping from the belt drive when the pulley is operational. The narrow configuration of the V belts ensures more wedge action in the pulley system as well as a higher drive belt capacity to withstand heavy loads.
