Rossi MR-IV-40-UO2A Worm Gearbox 70:1 Reducer

Rossi MR-IV-40-UO2A is a 70:1 worm gear reducer from Rossi Motoriduttori’s MR IV series, engineered to deliver high torque at low speed in a compact hollow-shaft package. This unit is rated for 0.25 kW and provides a 20 rpm output when driven by a suitable input, with a hollow output shaft that features an IEC 63 bore for straightforward coupling to a mating shaft or motor adapter. The MR-IV 40 variant houses a robust worm gear train inside a durable housing, offering reliable torque multiplication for demanding automation tasks while maintaining a compact footprint suitable for integrated gear-motor assemblies. Common applications include automation lines, conveyors, packaging equipment, and robotics where precise reduction and dependable performance are essential. The 70:1 ratio reduces motor speed to a slow, torquey output, enabling controlled motion without resorting to oversized drives. This reducer is designed for integration with compatible Rossi motors or other motors that accommodate a hollow-shaft interface, providing a straightforward path to upgrade performance in equipment that requires compact, high-torque low-speed drive solutions.
