S.ME.I., estalished in 1973, has over 25 years experience in manufacturing planetary gears of all types and for every application.

The RES - series gears are built to a modular design so that the various components can be assembled together, allowing for a vast range of models. With a relatively low number of componets, a high number of gearboxes can be constructed to meet even the most exacting requirements.18 different sizes of planery gears, all of them with modular design, are easy to assemble and cover a range of torque levels from 1.000 Nm to 500.000 Nm (740 to 370,000 lb.ft). The possible ratios, with up to 4 or more reduction stages, go from 3 to over 5,000.

Thanks to a high number of accessories, our products ca be "tailor-made" to meet customer requirements, such as couplings for hydraulic and electric motors, high speed shafts and multi-disc brakes. In addition, we offer a choice of in-line gears , right-angle gears and gearboxes with flange or foot mount. There are six types of output shafts equipped with specific accessories.

CNC manufacturing facilities guarantee high product quality at competitive prices. The QUALITY SYSTEM, conforms to UNI EN ISO 9001:2000 standards, and the development and production, which employ modern CAD/CAM technology, guarantee for high quality levels. The computer network interfacing all company departments allows for reduced processing times and allows for the shortest delivery terms possible. Quality, reliability and flexibility of the RES-series gears are known all over the world.
