The KFS Series Flange Mounted Solid Output Shaft Helical Bevel Gearbox with Shaft Input is specifically designed for industrial transmission systems requiring flange mounting, flexible shaft input, and high-efficiency right-angle power transmission. Featuring a solid shaft input, the gearbox can be directly connected to electric motors, hydraulic motors, belt drives, chain drives, or other external power sources. The flange-mounted structure provides high installation accuracy and excellent structural rigidity, while the solid output shaft ensures reliable torque transmission for heavy-duty industrial applications. Equipped with precision-ground helical bevel gears, the KFS Series delivers smooth operation, high transmission efficiency, compact construction, and outstanding load capacity. It is widely used in conveyors, lifting equipment, mining machinery, mixers, packaging machinery, and automated production systems. Output torque reaches up to 50,000 Nm, with motor power ranging from 0.12 kW to 200 kW, depending on configuration.
