See DetailsIn the late winter season, despite the biting cold, overseas customers' enthusiasm for high-performance, high-quality gearbox products remains undiminished. Recently, customers from Russia, Iran, and Australia visited Shanghai SGR Heavy Industry Machinery Co., Ltd. (SGR) to conduct in-depth discussions on the procurement of planetary gear reducers for sightseeing and tourist boats, and to conduct on-site inspections of China gearbox manufacturer SGR's R&D and manufacturing capabilities.

During the visit, the overseas business manager and technical engineers of SGR extended a warm welcome to the overseas customers and accompanied them throughout the tour of China gearbox manufacturer SGR's modern gearbox production workshop, R&D center, and product testing center.
As one of the most famous gearbox manufacturer in China, SGR has its own factory with the area of 15000㎡, which ensures full control over the entire production process—from raw material inspection and precision machining to final assembly and performance testing. This vertically integrated manufacturing capability enables SGR to maintain stringent quality standards, optimize lead times, and rapidly respond to customized customer requirements.
Equipped with advanced CNC gear grinding machines, heat treatment lines, and a state-of-the-art testing laboratory, the facility supports the mass production of high-precision planetary and worm gear reducers while guaranteeing consistency, reliability, and compliance with international standards such as ISO 9001 and AGMA.
At the site, the technical engineers provided a detailed introduction to SGR's two main product systems: the N-series planetary gear reducers and the C-series worm gear reducers. From material selection and heat treatment processes to precision gear grinding, assembly, and performance testing, they comprehensively demonstrated the products' high precision, high reliability, and excellent performance under harsh working conditions.
It’s worthy to mentioning that SGR highlighted its modular and customized production services, which can be tailored to specific needs.
During the discussions, customers from various countries engaged in detailed discussions with the SGR technical team of SGR on topics such as product performance parameters, installation compatibility, selection guidance, and typical application cases. They highly praised the quality stability, delivery response speed, and localized service capabilities of SGR gearboxes.
The Australian customer stated: "This visit allowed us to truly experience the technical expertise and systematic manufacturing capabilities of this established Chinese gearbox manufacturer. SGR's comprehensive supply chain collaboration and quality control system have given us strong confidence for future bulk purchases."
Russian and Iranian customers showed strong interest in the N-series planetary gearboxes suitable for propulsion or deck systems of sightseeing boats, particularly appreciating their compact structure, corrosion-resistant sealing design, and quiet operation. They also engaged in practical discussions regarding production capacity, resulting in a lively and efficient exchange of information at the event.
Actually, the China gearbox manufacturer SGR has assembled a research and development team comprised of doctoral graduates and senior engineers, who bring deep expertise in mechanical transmission theory, finite element analysis, tribology, and smart manufacturing systems.
This highly skilled team spearheads innovation across core technologies—from high-power-density planetary gear design and low-backlash control algorithms to integrated condition monitoring and predictive maintenance solutions. By combining academic rigor with decades of industrial application experience, the R&D group continuously refines SGR’s product performance, durability, and adaptability to demanding environments. Their work is further amplified through strategic collaborations with leading institutions , ensuring that SGR’s technological advancements remain at the forefront of global gearbox development trends.
Following the visit, both parties took a group photo in front of the SGR company building, capturing this fruitful moment of exchange. This series of visits not only deepened overseas customers' understanding of SGR's products and technological capabilities but also injected strong momentum into Hezhong Heavy Industry SGR's further expansion in the global high-end transmission market.
To date, the gear reducer products developed and manufactured by China gearbox manufacturer SGR have been exported to 26 overseas countries, covering major industrial markets in Asia, Europe, the Middle East, South America, and North America.
In the future, China gearbox manufacturer SGR will continue to focus on innovation in gearbox products, integrate upstream and downstream resources, and expand into overseas markets. We will provide domestic and international customers with higher-quality gearbox products and mechanical transmission solutions, empowering the high-quality development of global industry and manufacturing.(Author,SGR, Angie Zhang)
