Bonfiglioli F Series

Bonfiglioli F Series is a high-performance lineup of parallel shaft helical gearmotors and reducers, engineered for space-constrained industrial applications. Adopting an optimized modular design, this series balances compact size, high torque capacity, and stable operation, making it a reliable power transmission solution for both light-duty and heavy-duty scenarios across global industries.

Covering a comprehensive performance range, the F Series offers power outputs from 0.18kW to 200kW, output torque spanning 3Nm to 22,500Nm, and transmission ratios from 3.77:1 to 281.71:1 for basic models. Dual-combination variants extend the ratio to an impressive 31,434:1, meeting special low-speed requirements. Its core gears are made of low-carbon alloy steel, undergoing carbonitriding and precision grinding to achieve 60HRC tooth hardness, ensuring 98% maximum transmission efficiency, low noise, and stable meshing.

Available in 11 frame sizes from F..27 to F..157, the series supports versatile configurations like shaft extension, foot-mounted (F), flange-mounted (FF), and shaft-mounted (FA) types. The robust cast iron housing, coated with RAL7031 gray-blue anti-corrosion paint, provides excellent torsional rigidity and durability. Standard IP54/IP55 protection resists dust and moderate moisture, with optional upgrades for harsh environments.

Equipped with lifelong synthetic lubrication and dual-seal structures, it minimizes maintenance needs and prevents oil leakage. Compatible with IE3 to IE5 efficiency motors and variable speed drives, it enhances energy-saving performance. Widely applied in conveyors, mixers, pumps, and construction machinery, the F Series integrates flexibility, efficiency, and reliability, delivering cost-effective solutions for diverse industrial power transmission demands.
