It features a 1-1/4 inch size as specified in the product title, making it suitable for installations that require that dimension. As a dedicated timing pulley, it works with companion Gates timing belts to maintain proper tooth engagement and reduce belt slip in automated equipment and other machinery that rely on positive-drive belt systems.
