SEW ML..2 Series Helical And Bevel Helical Gear Unit

The SEW ML..2 Series Helical and Bevel Helical Gear Unit offers remarkable advantages tailored for heavy-duty industrial scenarios, standing out with its robust performance and adaptability. Crafted with a welded steel housing and split-line structure, it achieves an excellent balance of high rigidity, reduced weight, and easy maintenance—simplifying inspection and part replacement while withstanding intense vibration and heavy loads. Its gears, made from 18CrNiMo7-6 alloy steel with ISO 6+ precision and 59–61HRC hardness, ensure smooth meshing, ultra-low noise operation, and superior wear resistance, extending service life even in continuous high-torque work.

The modular design enhances flexibility, supporting diverse input/output connections and horizontal mounting to fit customized system configurations. Integrated lubrication and cooling systems enable stable operation in harsh environments with extreme temperatures, dust, and humidity. This series, available in fifteen sizes and seven models, delivers a torque range of 1.2 to 6.6 million lb-in, making it widely applicable in mining (conveyors, crushers), steel production (rolling mills), port operations (crane drives), and bulk material handling. It balances consistent efficiency, durability, and cost-effectiveness, requiring minimal downtime for maintenance. Backed by SEW’s global service network, it ensures reliable technical support and quick access to parts, meeting the rigorous demands of heavy-industry applications. (400 words)
