The KAS Series Hollow Output Shaft Helical Bevel Gearbox with Shaft Input is specifically designed for industrial transmission systems requiring flexible shaft input, direct hollow shaft mounting, 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 hollow output shaft enables direct mounting onto driven shafts, simplifying installation while reducing coupling components and maintenance costs. Combined with precision-ground helical bevel gears, the KAS Series delivers smooth operation, high transmission efficiency, compact construction, and outstanding torque capacity. It is widely used in conveyors, mixers, mining machinery, lifting equipment, 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.
