Potential Market Size of Reducers in China
According to industry experts and associations, global precision reducers used in robotic applications can be broadly categorized into three types: RV reducers, harmonic reducers, and SPINEA reducers. Of these, RV reducers and harmonic reducers each account for about 40% of the market share, while SPINEA reducers make up 20%. It is evident that RV and harmonic reducers are the mainstream precision reducers for industrial robots.
Characteristics of Different Reducers
-
RV Reducers: These reducers are known for their large reduction ratios, high transmission efficiency, excellent motion accuracy, minimal backlash, low vibration, high rigidity, and reliability. RV reducers are typically installed in heavy-load positions in joint robots, such as the shoulder, upper arm, and base.
-
Harmonic Reducers: These reducers have a high reduction ratio, compact size, fewer parts, and high transmission efficiency. In joint robots, harmonic reducers are generally placed in the lower arm, wrist, or hand sections.
As China’s industrial robot application market develops rapidly, the demand for reducers used in industrial robots has also been growing.
Market Demand for Reducers in China
By 2020, it was estimated that China would need approximately 190,000 robots annually, with each industrial robot requiring 4 to 6 reducers. Given that the typical lifespan of these reducers is only around 20,000 hours, replacements will be necessary. It is predicted that by 2020, the domestic market share of robots in China will reach 50% (95,000 units), and by 2025, this share will exceed 70%.
Future Potential Market
In the next five years, the potential market for robots and related services in China is expected to surpass $74 billion. This growth is driven by the rapid development of industrial automation and the increasing adoption of robots in manufacturing, logistics, and other sectors.
Overall, the market for reducers in China is poised for significant expansion, fueled by the increasing demand for robots and the continuous need for precision components like RV and harmonic reducers in various industrial applications.
