Bonfiglioli A Series
Bonfiglioli A Series, a flagship helical inline gear motor lineup from the Italian power transmission expert, stands out for modular design, robust performance, and wide场景 adaptability. Engineered to meet diverse industrial demands, this series integrates high-efficiency motors with precision gear units, becoming a reliable core component in global automation systems.
Covering a versatile performance spectrum, the A Series spans a power range of 0.12kW to 75kW and output torque from 50Nm to 12,000Nm, with transmission ratios ranging from 1.8:1 to 480:1. Available in 2-stage and 3-stage reduction configurations, it adopts hardened and ground helical gears, ensuring smooth meshing, low noise (≤72dB), and transmission efficiency up to 97%, ideal for continuous-duty operations.
The series features a torsionally rigid cast iron housing, offering excellent corrosion resistance and load-bearing capacity to withstand harsh industrial environments. Its modular architecture supports flexible mounting options—foot, flange, and hollow-shaft installations—enabling seamless integration with existing equipment. Optional accessories include electromagnetic brakes, forced lubrication systems, and IP67/IP69K protection, tailoring to special scenarios like food processing and outdoor applications.
Widely deployed in conveyors, packaging machinery, material handling, and construction equipment, the A Series excels in both standard and demanding conditions. Compatibility with variable speed drives enhances energy-saving potential, while long-life components and optimized lubrication reduce maintenance costs. Embodying Bonfiglioli’s decades of engineering expertise, this series balances reliability, efficiency, and customization, delivering cost-effective power transmission solutions for global industrial users.
Bonfiglioli A Series (Helical Bevel Gear Motors) Specifications
Note: A Series is a right-angle helical-bevel gear motor line with compact design, high efficiency, and wide torque/power coverage (0.22–150kW).
