The KAFS Series Flange Mounted Hollow Output Shaft Helical Bevel Gearbox with Shaft Input is specially engineered for industrial drive systems requiring high-precision flange mounting, flexible shaft input, direct hollow shaft connection, 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 housing provides excellent installation accuracy and structural rigidity, while the hollow output shaft allows direct mounting onto the driven shaft, reducing transmission components and simplifying maintenance. Equipped with precision-ground helical bevel gears, the KAFS Series offers smooth operation, high transmission efficiency, compact construction, outstanding torque capacity, and reliable long-term performance. It is widely used in conveyors, mining equipment, lifting machinery, mixers, packaging equipment, 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.
