EPNMRV 040 Worm Reducer

The EPNMRV 040 is the entry point into the standard industrial range of the EPNMRV series. At 40 mm centre distance, it offers the full ratio spread from 5:1 to 100:1 and accepts IEC 56 and 63 series motor flanges, making it compatible with the widest range of fractional-horsepower motors available in Australia. It is the most frequently specified model for general-purpose packaging, textile, and light food-processing equipment.

Where the EPNMRV 040 Is Used

Common deployments include carton erectors and sealers, small-format shrink wrapping machines, textile bobbin winders, label applicators, rotary filling heads, and light-duty screw conveyors for granular materials. In Australia, the EPNMRV 040 is a staple in packaging lines across western Sydney logistics hubs and small food production facilities in regional Victoria.

When to Choose This Model

Select the EPNMRV 040 when your output torque requirement is below 35 Nm continuous and you are using motors up to 0.37 kW. For applications requiring higher continuous torque or 71-frame motor flanges, the EPNMRV 050 provides the next step up in load capacity.

For detailed information on housing materials, worm gear efficiency characteristics, and installation orientation guidelines, refer to the EPNMRV Series overview.
