Worm Gear Reducers – VSF Series


Back to Worm Gear Reducers – VSF Series


The SW reducer, 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.
