multi-ribbed pulleys 40 multi-ribbed pulleys the combination of high-power capacity and low-profile design means the multi-ribbed drive can improve the drive design while lowering drive costs multi-ribbed pulleys and belts allow narrower mounting clearances need less center distance adjustment and require less take-up for tensioning additionally they allow the use of sheaves that are narrower in width and smaller in diameter without sacrificing power capacity smaller narrower sheaves mean a reduction in weight so more of the drive gets to the load for increased efficiency nylon pulley profile for ...
