Motovario NMRV Worm Reducers

Motovario NMRV worm reducers have led the industry in design innovation for more than 20 years.

By using aluminum housings, Motovario can produce worm reducers that are maintenance-free, have low occurrences of leaks, run at higher efficiency and are easier to handle than standard cast-iron worm reducers.

Using two bearings on the input shaft, o-rings instead of paper gaskets and painting the reducers limits problems caused by leaks, corrosion and vibration.

Motovario also hardens all worm shafts to improve efficiency and prolong reducer life.  Please refer to MVarioNMRVNRV.pdf.
