SW Series Worm Gearboxes

Round body multi-mount style worm gearboxes and geared motors

The SW reducer, which complements the Motovario NMRV gear reducer, has a shaft height between 30 and 90 mm and a compact round smooth body casing design that reduces the space as much as possible.  A wide range of mounting options including feet, torque arms and output flanges are available.

For better reliability and compatibility/effectiveness of supply, the gearing, the bearings, the motor flange and the accessories are those of the NMRV series.
