Varvel introduced a valuable and upgrading feature to the 'flexibility evolution': the strategic road map of the company's development in years to come.

The usual key-coupling between motor and gearbox was replaced by a customized type "G" elastic coupling without any increase in the geared motor dimensions.

The advantages of elastic coupling usage are:
- inventory reduction, just one reducer stocked for each ratio regardless input shafts;
- flexibility and stock-rotation increase;
- fretting corrosion elimination;
- zero backlash in motor/reducer fit;
- reduced heat transmission via motor shaft;
- high motor vibration damping.

The elastic coupling "G" is now available on:
- Worm speed reducers series RS from size 28 to 110;
- Worm speed reducers series RT, all sizes;
- Helical speed reducers series RD, all sizes;
- Shaft mounted parallel reducers series RN, all sizes;
- Bevel/helical reducers series RO e RV, all sizes.
