SEW M1..N Series Helical Gear Unit

The SEW M1..N Series Helical Gear Unit boasts prominent advantages that make it a versatile choice for both general and heavy-duty industrial applications. Its core strengths lie in precision-machined helical gears, which enable smooth power transmission, ultra-low operating noise, and exceptional load-bearing capacity—supporting continuous operation under fluctuating load conditions without compromising performance. The robust cast iron housing enhances rigidity and durability, effectively resisting vibration, impact, and harsh working environments such as high dust, moderate temperature variations, and humid settings.

This series offers remarkable flexibility with 2-, 3-, and 4-stage configurations, covering a broad gear ratio range to meet diverse speed and torque demands. It supports multiple mounting positions and seamless integration with various motors, facilitating customized system setups for different industrial scenarios. Optimized lubrication systems reduce friction and wear, minimizing maintenance requirements, operational downtime, and long-term costs. Widely applied in materials handling (conveyors, lifts), packaging machinery, manufacturing production lines, and light engineering, it excels at reliable power delivery. Backed by SEW’s global service network and strict quality control, it ensures stable performance, extended service life, and cost-effectiveness, catering to both standard operations and demanding industrial drive needs.

description

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.
