The SF Series Flange Mounted Solid Output Shaft Helical Worm Gearbox is designed for industrial applications requiring compact flange installation, high reduction ratios, smooth operation, and reliable torque transmission. Combining a helical gear pre-stage with a worm gear final stage, it delivers excellent torque density, stable low-speed performance, and optional self-locking capability. The Helical Worm Gearbox is widely used in automation equipment, lifting systems, and conveying machinery where compact structure and precise motion control are required. Output torque ranges up to 18,000 Nm, while input power capacities range from 0.12 kW to 90 kW depending on configuration.
