The DUO (Diagnostic Unit Oil Aging) is an intelligent monitoring device designed for gear unit drive systems. It adopts professional thermal analysis technology to real‑time track gear oil temperature and remaining service life, supporting online detection even during continuous production. Equipped with high‑precision thermal sensors and an evaluation module, the unit collects temperature data and automatically calculates residual oil lifespan based on oil specifications. Users can set custom threshold values to receive timely warning alerts when parameters go beyond limits. It helps enterprises precisely adjust maintenance intervals to match actual production workflows, simplify scheduling, and enhance machine operational efficiency and economic benefits. As a core part of condition monitoring solutions, DUO enables in-service diagnostics, predictive maintenance and reliable lifecycle management for industrial gear units.
Monitor gear unit temperature and residual lubricant service life of your drive systems effortlessly via thermal analysis – anytime, even during ongoing production. The measured data from the DUO unit enables you to perfectly align gear unit maintenance intervals with your actual operational processes. This simplifies process planning while boosting the overall efficiency and cost-effectiveness of your machinery and installations.
The DUO (Diagnostic Unit Oil Aging) performs continuous thermal analysis on gear unit lubricant. A precision thermal sensor captures real-time oil temperature and transmits data to the evaluation module, which calculates the remaining service life according to the specific oil grade used.
Simply set customized threshold values, and the DUO system will issue alert notifications once limits are exceeded. This allows you to keep constant track of residual oil life and the operating performance of your mechanical drive equipment.
As an ideal supporting solution for our gear units, the diagnostic unit enables in-operation oil life monitoring, real-time condition diagnostics and optimized maintenance scheduling. It serves as an essential element for professional condition monitoring strategies in industrial applications.
Professional coating and corrosion protection solutions enable SEW drive units to operate reliably in harsh and extreme industrial environments. Combining internal anti-corrosion treatment with high-performance surface coating technology, the integrated safeguard system delivers comprehensive protection for motors and gear units against moisture, oil, dirt and chemical erosion. Beyond standard protection levels, customized surface treatments and premium materials further enhance durability, allowing the equipment to adapt to diverse working conditions. It covers ordinary low-contamination scenarios as well as sites with frequent wet cleaning by acidic and alkaline agents. The surface protection portfolio ranges from standard grade to OS1, OS2 and OS3. The premium ASEPTICplus® package adopts OS4 protection as standard specification, realizing full-level corrosion resistance and long-term stable operation of drive systems in complex corrosive environments.
The Premium Extended Warranty Package delivers enhanced protection specifically designed for gearmotors. Building upon the standard 24-month factory warranty starting from the purchase date, this premium plan provides an additional 12 months of reliable coverage, offering customers prolonged security and peace of mind for their drive equipment. This extended warranty option is only available for newly purchased gearmotors and must be selected and confirmed at the time of original order placement; no subsequent retroactive enrollment is permitted. By opting for this premium protection package, users can effectively mitigate operational risk, reduce unexpected maintenance and repair costs, and ensure stable long-term performance of gearmotors. It serves as a cost-effective safeguard that optimizes equipment lifecycle management and maximizes the operational reliability and economic value of industrial drive systems.
SEW’s AMS, AQS, AESMS, and AESQS adapters provide compact, innovative mounting solutions for IEC/NEMA motors, servomotors, and stainless steel motors, enabling fast, safe installation. AMS/AQS adapters fit standard gear units, while AESMS/AESQS are for stainless steel gear units. AMS adapters support IEC/NEMA motors, are interchangeable with AM adapters, and reduce installation length by up to 37%.
