Restore smooth power transmission and precise speed regulation with the genuine-compatible Heidelberg Variable Speed Pulley (Part No. KS.100.048F / KS.100.048). Designed for main drive torque transmission on classic Heidelberg cylinder and letterpress-derived offset equipment, this variable speed expanding pulley allows dynamic speed adjustment during press operation. Its heavy-duty metal casting and machined sheaves resist pitch wear, heat buildup, and groove pitting, ensuring optimal belt traction and steady press cycles even under continuous multi-shift operation.
