V-belt drive systems are an economical option for industrial, automotive, commercial, agricultural, and home appliance applications. A V-belt system can transmit more power than a flat belt system without slip due to increased friction. The pulleys in this system play an important part in maintaining the tension required to drive the transmission. It’s important to periodically check pulley conditions. If your pulleys are worn, Zoro offers a wide variety of replacement pulleys to prolong belt life and keep power consistent and dependable. Zoro also carries idler pulleys that interact with either the wedged or flat side of the V-belt, variable pitch V-belt pulleys that are used on fans, blowers, and industrial water and trash pump applications, and timing belt pulleys that are used in applications where the positional relationship of the driving pulley to the driven pulley must remain constant.
