Uncle Zhang Discusses Leading Robot Actuators: Can These Stocks ‘Move’ Opportunities Amid the Wave of Smart Manufacturing?

Stock friends, Uncle Zhang is back to chat with everyone! Recently, the robot actuator concept sector has been quite lively in the market, with many related stocks showing impressive performance. Today, let’s have a good discussion about the robot actuator track—first, we’ll talk about how it was speculated in the past, then look at the new situation in 2025, and finally highlight the top 10 core leaders to see who has real capabilities and who should be avoided!

1. Past Speculation of Robot Actuator Concepts: From ‘Concept Emergence’ to ‘Gradual Focus’

Robot actuators are key components for robots to perform various actions, including harmonic reducers and servo motors, which are essential in industrial and service robots. The speculation in the A-share market has gone through several stages:

First Wave (2015 – 2018): ‘Initial Concept, Broad Speculation’

At that time, the robot concept had just started to gain popularity, and robot actuators as a niche area were not widely recognized. Any company related to robots, regardless of whether they had actual actuator business, could see their stock prices driven up by funds, belonging to the ‘big robot concept’ speculation. Actuator stocks benefited from this, but they rose quickly and fell just as fast, lacking fundamental support.

Second Wave (2019 – 2023): ‘Focusing on Core Components, Assessing Technical Strength’

With the popularization of industrial robots, the market began to pay attention to core components like actuators, and the speculation logic changed. It started to focus on ‘which companies have core actuator technologies (such as the precision of harmonic reducers and the performance of servo motors)’, ‘can they produce in bulk’, and ‘are their downstream customers leading robot companies’. Companies with core technologies that can supply major robot manufacturers would see their stock prices steadily rise; those without technology, merely riding the concept, would quickly be eliminated by the market.

2. Robot Actuators in 2025: Demand Explosion + Data Support

In 2025, the robot actuator market will experience a significant explosion:

• Industrial Robot SectorDomestic industrial robot production is expected to grow by 40% year-on-year, with each industrial robot requiring multiple actuators, such as harmonic reducers and servo motors, directly driving actuator demand;
• Service Robot SectorService robot sales are projected to increase by 55% year-on-year, with a significant rise in demand for small, high-precision actuators for delivery robots and cleaning robots;
• Technological AspectsDomestic actuator technology has made significant progress, with the precision of harmonic reducers reaching about 90% of foreign brands, and servo motors nearing international levels in response speed and stability, accelerating domestic substitution.

From the data, the domestic robot actuator market is expected to grow by 50% year-on-year in 2025, reaching [X] billion yuan, indicating a strong industry development momentum.

4. Uncle Zhang’s Summary: How to Invest in Robot Actuator Stocks Now?

Stock friends, from the analysis above, it can be seen that the robot actuator sector currently has favorable conditions such as explosive downstream demand and accelerated domestic substitution, but there are also risks. Uncle Zhang offers a few suggestions:

First, look for ‘real technology, real products, real demand’: Avoid companies that merely ride the concept without actual actuator business; choose those like Luyuan Harmonic that have core technology, actual products, and clear downstream demand;

Second, focus on ‘field coverage + technical barriers’: Prioritize companies that can cover high-growth areas like industrial robots and service robots, or those with barriers in core actuator technologies (such as harmonic reducer precision and servo motor performance);

Third, be wary of ‘technical risks + industry competition risks’: The technical threshold for actuators is high, and domestic companies still lag behind international giants. As industry competition intensifies, it is crucial to understand a company’s technological reserves and market competitiveness before investing, avoiding blind chasing of high prices.

Finally, as the old saying goes, the stock market has risks, and investment requires caution! The robot actuator stocks currently seem to have opportunities, but one must keep a keen eye to choose wisely, hoping everyone can select the right stocks and earn steadily!
