I. Control and Drive Components: Leading Domestic Brands Have Overtaken Importers
Control and drive components are the main battleground for domestic production. According to MIR Industrial Data, in 2025, in my country’s general-purpose servo market, Huichuan Technology ranked first with a market share of approximately 30.5%, followed by Siemens and Panasonic with approximately 8.9% and 7.0% respectively.
Leading domestic brands have already overtaken imported brands in market share. In the low-voltage electrical appliance sector, Chint Electric is one of the strongest domestic brands in terms of overall strength.
When choosing control and drive components, leading domestic manufacturers have a clear advantage in terms of cost-effectiveness and delivery time.
II. Precision Transmission Components: Domestic Leaders in Robot Joints
In the robotics and precision transmission sector, domestic leaders are rapidly emerging.
According to industry data, Estun adheres to a full-industry chain self-sufficiency strategy, with a self-sufficiency rate of over 95% for core robot components. Its domestic industrial robot shipments have ranked first among domestic brands for many consecutive years. In the harmonic reducer field, GreenTech’s harmonic technology holds a leading market share domestically, while Laifu Harmonic ranks second among Chinese harmonic reducer providers based on 2025 shipments, with a market share of approximately 21.4%.

Sensing Sensors: High-End Achieves Large-Scale Breakthrough
In the sensing and sensor sector, high-end domestic products have achieved large-scale breakthroughs.
According to the MIR Rui Industrial White Paper, Kunwei Technology topped the Chinese six-dimensional force sensor market with approximately 53% market share; according to data from the Gaogong Robotics Industry Research Institute, BluePoint Touch Technology captured approximately 72.6% of the domestic humanoid robot six-dimensional force sensor market share.
Domestically produced force control and vision-related core components are breaking the long-term monopoly of overseas brands on high-end parts, becoming an important choice for equipment manufacturers to reduce costs and improve quality.
IV. Basic Components: A Dense Cluster of Sub-Segment Champions
In the basic component segment, such as bearings, lead screws, and castings, there is a dense cluster of sub-segment champions.
According to public data, Wanda Bearings holds the leading domestic market share in forklift bearings and participates in drafting industry standards; Henggong Precision holds approximately 63% of the domestic market share in horizontal continuous ductile iron castings; and several companies with domestic substitution capabilities have emerged in linear transmission components such as planetary roller screws and ball screws.
The mass localization of basic components is providing a more stable supply chain guarantee for OEMs.
V.
Selecting Models Based on Segment Requirements
The recommended logic should be “selecting models based on segment requirements.”
Based on procurement experience, selecting component manufacturers doesn’t require pursuing a single brand to dominate: for control and drive components, prioritize leading domestic companies (such as Inovance) to achieve a balance between performance and price; for precision transmission and force control sensing, examine the champions in each sub-segment, combining accuracy, lifespan, and supply stability for a comprehensive comparison;
for basic components, focus on verifying quality traceability and delivery timeliness.
The key is to align the leading players in each segment with your own needs, rather than blindly following a single ranking list.
Conclusion
From a trend perspective, domestic automation components are moving from substitution to leadership.
According to industry research, the market size of China’s automation equipment components industry will reach approximately 308.46 billion yuan in 2025, representing a year-on-year growth of approximately 9.5%, with continued strong demand from new energy, semiconductor, and robotics applications.
With leading domestic companies and sub-segment champions having saturated order books and expanding production capacity, this presents a window of opportunity for equipment manufacturers to optimize their domestic supply chains and lock in costs and delivery times.
