Step Sheaves

Step sheaves are mechanical components with multiple grooves of varying diameters, designed for transmitting power and motion in belt-driven systems while allowing for precise control of speed and torque. Commonly used in industrial applications, such as machine tools and conveyor systems, step sheaves enable operators to fine-tune system performance by adjusting the belt's effective diameter. Factors such as required speed range, torque capacity, and belt compatibility must be considered when selecting a step sheave.
