SITI MI-50-F Worm Gearbox with 0.25kW Motor, Ratio 40:1

The SITI MI-50-F is a compact worm gear reducer integrated with a 0.25kW (0.34HP) electric motor, designed for reliable torque transmission in industrial applications. This gearmotor features a 40:1 reduction ratio, providing high torque output at reduced speeds, ideal for conveyor systems, packaging machinery, mixers, and other automation equipment requiring precise speed control and durability. Manufactured by SITI S.p.A. in Italy, it boasts a robust aluminum housing for corrosion resistance and efficient heat dissipation, ensuring long service life even in demanding environments. Key advantages include low noise operation, high efficiency (up to 80% depending on ratio), and easy maintenance with modular design for quick repairs. Compared to similar products like those from Bonfiglioli or SEW-Eurodrive, the MI-50-F offers cost-effective performance with comparable torque ratings but in a more compact footprint, making it suitable for space-constrained installations. Drawbacks may include lower efficiency at higher ratios compared to helical gears and potential backlash in high-precision applications. Based on attached images, this unit appears used with visible wear, dirt, and minor surface corrosion, but no major damage; it includes a yellow power cable and flange mounting. Applications span food processing, material handling, and light manufacturing. For optimal performance, pair with variable frequency drives for speed adjustment.
