SEW Eurodrive low-maintenance M1 series industrial gear units are dimensioned for specific applications that require a small gear ratio range from i = 1 to i = 7.1. The M1..N series industrial gear units were developed especially for applications that require a small gear ratio range. This ensures that you are using the perfect helical gear unit for your application. This areas of application typical for this series are drive solutions that require foot-mounted helical gear units. You can use this gear unit for pump applications or rollers and refiners in the paper industry in particular. As a leading industrial gear unit manufacturer, one of our main focal areas is engineering low-maintenance gear units for you. The M1..N series single-stage helical gear units are easy to remove because the steel housing is split horizontally. This means major savings on time and money in case you require service. We will also finish all of our gear units with special surface and corrosion protection as required. This allows you to use your gear units in extremely moist and/or chemically aggressive environments.
