MERGER: The transmission of an idea

Genesis: A speed reducer allows you to modify the speed of an electric motor by adapting the characteristics of the input and output shaft. Thus, this product allows you to increase the torque: the maximum and minimum torque supported is expressed in newton-meters (Nm).

As usage constraints have evolved, choosing a speed reducer is no longer simply a matter of consulting a catalogue.

MERGER , one of the leading European manufacturers of motorization components, is committed to involving its engineers and technicians with your design office to better guide your selection towards the most suitable speed reducer.

In addition to manufacturing a very complete range of speed reducers, MERGER also produces industrial gearboxes, as well as any special reducer and multiplier for very specific and diverse applications.

We specialize in repairing all brands: ACMI, BENZLER, BRAMPTON-RENOLD, BREVINI, CATEP, CITROEN MESSIAN, CLECIM, COUPE HUGOT SURETEX, CMD, COMELOR, DANFOSS, DANIELLI, DAVID BROWN, DEMAG, DODGE, ELLI, FALK, FENNER , FLENDER, FOC, GIRARD, GUIBE, HANSEN, JAHNEL-KESTERMANN, KISSLING, KRUPP, LUFKIN, MERGER, METSO, NORD REDUCTEUR, PEKRUN, PIV, PUILLES FRERES, PTP, REGIANNA, RENOLD, ROSSI, SANTASALO, SAWA, SEW, SUMITOMO , THYSSEN, WECO, WEG, ZOLLERN…; and all parts: casings, shafts, pinions, couplings, gears, covers, inspection hatches, bearings, seals, etc.

You have a project, need to replace your equipment, you can send us your specifications, the serial number of your equipment or a photo of your installation so that we can guide you.
