An introduction of the reducer factory SGR

Those customers who are familiar with SGR know that SGR is a direct-source manufacturer of gear reducers. Leveraging the inherent advantages of being a primary factory, the reducers developed and produced by SGR boast a comprehensive range of models, superior quality, customizable production options, and exceptional cost-effectiveness.

Today, we invite you to step inside the SGR facility—our direct-source factory—to uncover the manufacturing secrets of this long-established speed reducer manufacturer in China.

Advanced design philosophy

The reducer factory SGR boasts a highly skilled and capable R&D and design team. Comprising doctoral candidates and senior engineers spanning multidisciplinary fields—including mechanical engineering and electrical control—the team possesses a solid foundation in mechanical transmission theory combined with extensive practical engineering experience. Actively participating in industry associations and technical exchange initiatives, the team works to integrate innovative industry advancements into mainstream reducer technology solutions.

For instance, the N-series planetary gear reducer developed and manufactured by SGR feature gears crafted from 20CrMnTi alloy steel that undergo carburizing, quenching, and precision grinding processes. These units offer numerous advantages, including multi-tooth load sharing, smooth and reliable operation, and high mechanical efficiency. The design philosophy and manufacturing techniques behind the N-series planetary gear reducers align with those of leading international reducer brands, enabling them to serve as direct replacements for equivalent products from global manufacturers such as Brevini, Dynamic, Rossi, and Bonfiglioli.

SGR’s own factory with abundant equipment

The reducer factory SGR operates its own factory, spanning an area of15,000 square meters. The facility is equipped with advanced professional machinery, including a four-shaft linkage complex surface CNC grinding machine,vertical and horizontal machining centers, gear machine tools, and CNC vertical turning centers, as well as various other general and specialized machines.

The reducer factory SGR also possesses the first toroidal worm precision measuring instrument in China, a world-leading device capable of measuring toroidal worms with Grade 4 precision—thereby ensuring that the tooth profile geometry meets DNV/ISO standards.

The reducer factory SGR is also equipped with a comprehensive array of testing equipment,including coordinate measuring machines, micro-hardness testers, geometric precision measuring instruments, and reducer power performance test benches, thereby establishing leading technical capabilities and a specialized system that integrates design, production, and technical services.

Rigorous quality control system

SGR has obtained ISO 9001 quality system certification and strictly adheres to the standard requirements of the ISO 9001 quality management system throughout every stage of the manufacturing process. From the inspection of incoming raw materials and the control of critical production steps to the final factory testing of complete units, SGR places great emphasis on every single detail, thereby providing a robust guarantee for the stable performance of its planetary and worm gear reducers.

Precisely by virtue of rigorous quality control and management, as early as 2009, the N-series planetary gear reducer was awarded the "First Prize for Scientific and Technological Achievements in the Gear Industry" by the China Gear Professional Association; furthermore, it was recognized as a "Shanghai High-Tech Achievement Transformation Project" and secured an invention patent.

A manufacturing system dedicated to continuous improvement

In the realm of high-end transmission manufacturing, SGR seamlessly integrates lean manufacturing principles with precision manufacturing technologies, driving the evolution of gear transmission products toward a trajectory characterized by compactness, modularity, standardization, low vibration, and low noise.

During the initial consultation phase,  SGR deployed a 3D reducer selection system to assist customers in efficiently and conveniently identifying the most suitable products.

Furthermore, from the moment an order is received, the SGR factory activates a highly efficient collaborative mechanism: technical specifications are rapidly confirmed, critical components are prepared with precision, and high-precision gear heat treatment and grinding processes are seamlessly integrated. Through assembly line operations and 100% factory run-in testing, we ensure that every reducer is stable, reliable, and delivered on schedule—thereby upholding our corporate mission of "Responsibility, Communication, and Progress."

Leveraging the stability of its reducer products and a consistently excellent reputation,  SGR reducers are exported to 31 countries and regions—including Europe, the Americas, Australia, and the Middle East—steadily expanding our global client base. Moving forward, we will remain steadfast in our commitment to product quality and integrity, continuing to provide high-quality reducers to customers worldwide and striving to become a leading innovator in the field of mechanical transmission technology.
