Bonfiglioli C Series

Bonfiglioli C Series is a versatile lineup of helical inline gearmotors and reducers, encompassing C, CE, and CR sub-types to cater to a wide spectrum of industrial power transmission needs. Engineered with Bonfiglioli’s signature precision and durability, this series stands out for its exceptional efficiency, compact footprint, and flexible adaptability, making it a staple in diverse sectors ranging from light-duty machinery to heavy industrial equipment.

Covering an extensive performance range, the C Series delivers power outputs from 0.08kW to 213kW, output torque spanning 45Nm to 12,000Nm, and transmission ratios from 2.6:1 to 23,401:1. This broad parameter range is achieved through 2-stage, 3-stage, and 4-stage reduction configurations, enabling precise speed regulation for both low-torque and high-torque applications. The core helical gears undergo carburizing, quenching, and precision grinding, ensuring hardened tooth flanks (HRC58-62) that facilitate smooth meshing, low noise operation, and an impressive transmission efficiency of up to 98%.

Each sub-type within the series serves distinct needs: the standard C type offers a balance of performance and cost-effectiveness for general industrial use; the CE type features enhanced structural rigidity for heavy-duty scenarios; and the CR type is optimized for compact installations with space constraints. All variants adopt a robust cast iron housing, providing excellent torsional stiffness and corrosion resistance, with standard IP54/IP55 protection rating to withstand dust and moderate moisture in industrial environments.

The series supports flexible mounting options, including foot, flange, and hollow-shaft installations, enabling seamless integration with existing equipment. Compatible with variable speed drives and IE2 to IE5 efficiency class motors, it further enhances energy-saving potential. Widely deployed in conveyors, mixers, pumps, and material handling systems, the C Series combines low maintenance requirements, long service life, and modular customization, delivering reliable, cost-effective solutions for global industrial users.
