NGC Group

What NGC Group does

NGC Group, legally Nanjing High Speed Gear Manufacturing Co., Ltd. (南京高速齿轮制造有限公司), was founded in 1969 and is headquartered in Nanjing, China, operating as a wholly-owned subsidiary of Hong Kong-listed China High Speed Transmission Equipment Group Co., Ltd. (00658.HK). The company employs 5,001–10,000 people across five wholly-owned operating subsidiaries covering wind energy, industrial, rail, robot reducers (NGCRV), and new energy vehicle transmissions. NGC sells directly to enterprise OEMs in wind energy (Goldwind and others), rail transit (metros in China, Europe, Americas, South Africa, Australia, Brazil, Tunisia), heavy industry (Baowu, CITIC, Masteel, Lu'an Chemical), robotics/CNC (industrial robot manufacturers and machine tool builders), and new energy vehicles (passenger and commercial EV producers), with regional headquarters in Duisburg (Germany, since 2014), the Americas, and India (since 2025) and a sales footprint in 30+ countries.

The technology backbone is a proprietary gearbox and drivetrain platform spanning 2MW to 20+MW classes, anchored by journal bearing technology (10,000+ units shipped), fully integrated drivetrain platforms achieving torque density above 270 Nm/kg, composite profile modification, and advanced coating techniques for durability. Differentiated products include the offshore 16MW front-integrated DFIG gearbox (Wind Power Monthly Gold, 2025), the 20MW offshore wind drivetrain (2024 Gold award), the new MCPRV-S high-torque RV reducer for robotics, the 2250kW tower mill permanent magnet-gear drive system, and the 22-meter ring rolling machine main gearbox. The GearSight IoT cloud platform, CMMI Level 3 certified, provides hardware-plus-software condition monitoring, anomaly detection, and diagnostic services as an add-on across the installed base.

NGC generates revenue primarily through hardware sales under quote-based B2B contracts with enterprise OEMs and project owners, supplemented by managed-services revenue from GearSight monitoring and aftermarket O&M. H1 2025 revenue was RMB 9,978,981,000 (an annualized run-rate near RMB 20 billion), representing a 1.8% YoY decline; gross margin was 18.6% and the company recorded a loss of ~RMB 136 million attributable to owners, indicating cyclical pressure in core wind and rail end-markets despite ongoing product launches and a substantial pipeline of new product introductions scheduled for 2026 mass production.
