The current development status of China's precision reducer industry
A reducer is an independent component composed of gear transmission, worm drive, and gear worm drive enclosed in a rigid shell, commonly used as a reduction transmission device between the prime mover and the working machine. Precision reducers have the characteristics of small size, light weight, high precision, and strong stability, which can achieve precise control of mechanical transmission. They are mainly used in high-end manufacturing fields such as robots, new energy equipment, high-end machine tools, electronic equipment, printing machinery, etc. The mainstream precision reducers include precision planetary reducers, RV reducers, and harmonic reducers.

The upstream of precision reducers includes production enterprises of steel, aluminum, bearings, processing and testing equipment, cutting tools, and fixtures. The midstream mainly focuses on the production and manufacturing of precision reducers, while the downstream mainly includes high-end equipment manufacturers in dozens of industries such as robots, new energy equipment, engineering machinery, high-end machine tools, intelligent transportation, and electronic equipment.

With the strengthening of downstream customer demand in China and the gradual digestion of their own technology leading to improved product quality, some companies' reducer products have reached international standards. Domestic reducer companies are gradually breaking the monopoly of foreign companies and occupying a place in the market. The localization of precision reducer products has become an inevitable trend in industrial development, and domestic reducer enterprises will usher in good development opportunities.

Overall market size
The market size of Chinese reducers is expected to exceed 150 billion yuan by 2025, with a compound annual growth rate of about 5%. Among them, precision reducers (including harmonic, RV, and planetary reducers), as the high-end core category, have a significantly higher growth rate than the industry average. The market size of precision reducers has exceeded 2 billion yuan in 2023, and it is expected to reach a new high of 1710 yuan in 2025.

Segmented field growth

Harmonic reducer: Sales of 1.011 million units in 2023 are expected to increase to 1.19 million units by 2025, mainly benefiting from a 79% increase in demand for light-duty robots (such as 3C and consumer electronics robotic arms).

RV reducer: The sales growth rate of top enterprises in 2024 will reach 65% (such as Qinchuan Machine Tool), and the domestic RV market for robots is expected to reach nearly 4 billion yuan by 2025.

Planetary reducer: The global market is steadily expanding, with sales expected to reach 1.471 billion US dollars in 2025, but the localization rate of high-end products is still less than 30%.

Domestic substitution acceleration

Harmonic field: Green harmonic has a market share of over 60% and a lifespan of 8000 hours (exceeding international standards by 33%), entering Tesla's supply chain and achieving exclusive supply for finger joints.

In the RV field, the localization rate of dual ring transmission and Qinchuan machine tools has been increased to 20% -25%, breaking through bottleneck technologies such as gear shaping and tool localization, and achieving international leading performance of 189.

Technological innovation direction

Structural optimization: Dong'an Power has developed a planetary gear system reduction differential mechanism to achieve compactness and high transmission ratio; Demai Precision has launched a harmonic reducer with built-in compression function to solve the problem of spline deviation.

Intelligence and integration: Zhongdalide and other enterprises have launched an integrated machine of "reducer+servo motor", with an accuracy of 3-5 arc minutes and a cost 20% -30% lower than imports.

Green Manufacturing: Lightweight materials (such as high-strength aluminum alloys) and optimized gear design to reduce energy consumption and respond to the "dual carbon" goal
