Description
Step Pulleys are a type of V-Belt Sheave with multiple steps or diameters. Each step corresponds to a different speed ratio, allowing for variable speed transmission by moving the belt between different steps on the pulley. By changing the position of the belt on the steps, the rotational speed of the driven machinery can be adjusted to suit different requirements or tasks. Step pulleys are often found in manual or semi-automatic machines where variable speed control is necessary such as lathes, drills & milling machines
