Ghirri Mrv20 F1 Gear Reducer

The Ghirri MRV20 F1 Gear Reducer is a compact right-angle worm gear reducer that lowers input speed while multiplying output torque for industrial power transmission tasks. It is commonly installed in conveyors, packaging machinery, material handling equipment, screw conveyors, and automated production systems that require reliable 90-degree power transfer. The unit features an aluminum housing for continuous-duty service and a 90° shaft orientation with an F1 flange mounting configuration, offering multiple mounting positions. Key details include an output bore of 3/4 in and a secondary bore of 15/16 in, with oil-lubricated enclosed gearbox construction. The MRV20 series, manufactured by Ghirri Motoriduttori in Italy, carries part number MRV20 F1 and supports typical reduction ratios from 7.5:1 up to 100:1 depending on the chosen ratio and input speed. This gear reducer is used by maintenance teams and system integrators for repairs, drive system upgrades, and replacement of worn gearboxes in industrial machinery, delivering a compact footprint without sacrificing torque in demanding environments.
