NGC Wind Energy Gearboxes: Decades of Innovation, Global Reliability

With over two decades of dedicated focus on the research, development, and manufacturing of wind energy gearboxes, NGC has established itself as a trusted leader in the global wind power industry. Through unwavering commitment to technological innovation and in-depth adaptation to the evolving demands of the wind energy sector, our gearboxes have been engineered to deliver a competitive combination of high reliability, exceptional torque density, superior efficiency, and cost-effectiveness—core advantages that underpin their widespread adoption worldwide.

To ensure compliance with the strictest industry standards, our products have successfully obtained certifications from a comprehensive list of authoritative domestic and international institutions, including DNV, UL, TUV-NORD, TUV-SUD, CCS, CGC, CQC, ETL, and CE. These certifications serve as a testament to our rigorous quality control system and product performance. To date, we have supplied more than 125,000 main gearboxes to renowned wind turbine OEMs, all of which are operating stably and reliably at wind farms across more than 30 countries, spanning diverse geographical and climatic conditions.

We firmly believe that reliable products are forged through continuous technological upgrades, relentless innovation, and rigorous validation of every component throughout the development lifecycle. In the design of our main gearboxes, we take a pragmatic approach by fully integrating the actual operating conditions of wind turbines into the design framework. Based on precise load spectrum data, our engineering team conducts meticulous systematic calculations and in-depth analyses of each gearbox component, leaving no room for compromise in performance and durability.

Beyond theoretical design, we subject our products to a series of rigorous verification tests that closely simulate real-world operating scenarios. These tests include no-load performance tests, full-load operation tests, overspeed and overload endurance tests, extreme load resistance tests, accelerated life tests, and low-temperature adaptation tests. Such comprehensive testing ensures that our gearboxes can withstand the harshest and most unpredictable conditions, delivering consistent performance throughout their service life.

NGC StanGear and NGC WinGear Wind Energy Main Gearbox Platforms

After years of iterative research and market validation, NGC’s wind energy main gearboxes have evolved into two core product platforms: NGC StanGear and NGC WinGear. Each platform is tailored to optimize gear transmission performance, with StanGear adopting rolling bearings and WinGear utilizing sliding bearings for their planetary gear systems. This differentiated design ensures that both platforms seamlessly integrate into wind turbine transmission systems, guaranteeing safe, efficient, and long-term reliable operation of the entire unit.

To cater to diverse customer needs, both product platforms offer two model categories: SMG standard models and CMG custom models. The SMG series is designed for universal applicability, boasting mature technology that delivers higher reliability, shorter development cycles, and more competitive cost advantages—ideal for customers seeking stable, cost-efficient solutions. The CMG series, by contrast, represents our next-generation custom-developed products, engineered to meet the unique technical requirements, performance targets, and application scenarios of individual customers, showcasing our flexibility and R&D capabilities.
