Rossi Motoriduttori R 21 63 UP2A Gearbox Reducer

The Rossi R 21 63 UP2A Gearbox Reducer is a compact, shaft-mounted reduction unit designed to be paired with a drive motor via Rossi’s UP2A mounting interface. It delivers a fixed 15.8:1 reduction ratio, enabling slower output speed and higher torque at the driven shaft. As a standalone gearbox (no motor included), it is intended for integration into automated drive trains that use the UP2A interface for standardized mounting and torque transmission. Rossi gear reducers are manufactured by Rossi S.p.A., a company of the Moovimenta Group, and the UP2A designation identifies a specific Rossi mounting configuration used across the G-series family.
