The FA Series Hollow Output Shaft Parallel Shaft Helical Gearbox is specially engineered for industrial drive systems requiring compact installation, direct hollow shaft connection, and high-efficiency parallel shaft power transmission. Featuring a precision-ground parallel shaft helical gear design, the gearbox provides smooth operation, low noise, high transmission efficiency, and outstanding load capacity. The hollow output shaft allows direct mounting onto the driven shaft, eliminating additional couplings and reducing installation complexity while improving transmission reliability. Available with both foot-mounted and flange-mounted configurations, the FA Series parallel shaft helical gearbox is suitable for a wide range of industrial applications including conveyors, material handling systems, packaging machinery, lifting equipment, mixers, environmental protection 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 model configuration.
