The SFS Series Flange Mounted Solid Output Shaft Helical Worm Gearbox with Shaft Input is designed for industrial applications requiring flange-mounted installation, direct shaft input connection, high reduction ratios, and reliable torque transmission. The shaft input configuration enables direct coupling to upstream drive shafts, while the flange-mounted structure allows compact equipment integration. Combined with a helical gear pre-stage and worm gear final stage, the gearbox provides smooth operation, stable torque output, and optional self-locking capability. It is widely used in conveying systems, processing machinery, packaging equipment, and industrial automation applications. Output torque ranges up to 20,000 Nm, while input power capacities range from 0.12 kW to 110 kW depending on configuration.
