Worm gear reducers, combined and with pre-stage reduction unit
Series: SW - ISW - PC

Traditionally known as the producer of a wide range of mechanical variators and helical cast iron inline geared motor units, Spaggiari Trasmissioni expanded its product range, after being taken over by Motovario, by adding an aluminium worm gear unit named SW. This new product, which complements the Motovario NMRV gear reducer, has a shaft height between 30 and 110 mm (Baugrößen 030 bis 105) and a compact round smooth body casing design that reduces the space as much as possible. For better reliability and compatibility/effectiveness of supply, the gearing, the bearings, the motor flange and the accessories are those of the NMRV series.
