The FF Series Flange Mounted Solid Output Shaft Parallel Shaft Helical Gearbox is specially engineered for industrial transmission systems requiring high-precision flange mounting, solid output shaft transmission, and high-efficiency parallel shaft power transfer. Featuring a compact parallel shaft design and precision-ground helical gears, the gearbox delivers smooth operation, high transmission efficiency, low operating noise, and outstanding load capacity. The flange-mounted configuration provides accurate installation and excellent structural rigidity, while the solid output shaft ensures stable torque transmission for demanding industrial applications. Compatible with IEC motors or solid shaft inputs, the FF Series is widely used in conveyors, lifting equipment, packaging machinery, material handling systems, mixers, mining machinery, and automated production lines. Output torque reaches up to 20,000 Nm, with motor power ranging from 0.12 kW to 200 kW, depending on configuration.
