Rossi S.p.A. MR-IV-32-UO3A Worm Gearbox Reducer

Rossi S.p.A. MR-IV-32-UO3A Worm Gearbox Reducer is a compact MR IV-series worm gear stage, identified as the 32-size variant with worm extension UO3A. It delivers an 82.9:1 reduction ratio and is configured for integration with servo-motor systems that use an IEC 63 hollow output shaft, featuring a B5 mounting flange and an 11x140 interface footprint. This variant’s designation (MR-IV-32-UO3A) reflects the specific worm-gear arrangement and shaft configuration used within Rossi’s A-series catalog, ensuring consistent mounting geometry with other MR IV 32 models. Designed as a gearbox-only component, it is intended for automated-drive applications where a high reduction in a compact package is required and where coupling to a 63 mm shaft standard is desired for straightforward motor compatibility.
