The SW reducer, which complements the NMRV gear reducer, has a shaft height between 30 and 110 mm 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.
