The offered Plastic Pulley is commonly used in power transmission, fitness equipment and motor transfer applications, among other industries. These pulleys are well-suited for high-speed belt idlers found in the lawn and garden industry along with conveyors. Pulleys with two grooves are for use where multiple pulleys move a single load, such as block and tackle systems. The offered Plastic pulley is useful in applications with weight constraints. These pulleys spin freely on built-in ball bearings to maintain tension for reduced wear and vibration.
