I. FA Professional Platforms are the Main Channel
FA professional platforms are the main channel for standard parts. According to publicly available information from these platforms, Yiheda has over 2.8 million SKUs, covering 205 major categories and 4025 subcategories, with 90% of standard parts shipped within 3 days, and supports non-standard custom orders based on provided drawings;
Misumi provides approximately 600,000 standardized mechanical parts and a vast library of 3D models for download; JLCPCB FA focuses on one-stop procurement of mechanical and electrical parts; Aihefa covers transmission components such as synchronous pulleys, lead screws, and guide rails through a self-produced and direct-sales model.

MRO Platforms Manage Spare Parts Procurement
MRO platforms are responsible for the centralized procurement of spare parts.
According to industry data, Zhenkunxing boasts 32 advantageous product lines, over 27 million SKUs, and has accumulated over 180,000 cooperative clients, ranking first in China’s industrial equipment MRO market with an 11.2% market share; JD Industry follows closely with a 9.8% share, and its revenue in 2025 reached 23.952 billion yuan; Xiyu accounts for 5.3%.
Using MRO platforms for spare parts, general consumables, and administrative supplies can significantly reduce sourcing costs.
III. Brand Mall Covers Electrical Components
The brand original equipment manufacturer (OEM) mall covers electrical and control components.
According to platform information, Shenzhen Automation Mall gathers globally renowned brands such as SMC, Airtac, Omron, and Keyence, offering genuine products including PLCs, inverters, sensors, cylinders, solenoid valves, linear modules, and other full-series products; Nidec provides brushless motors, cooling fans, and other products through the Ameya360 electronic components platform; Buydao Sensor Network focuses on AI-powered rapid selection of industrial sensors from over 400 brands and millions of models.
IV. Supplementing with Comprehensive Platforms
Comprehensive platforms supplement MRO malls.
According to industry reviews, RS China is a one-stop procurement platform for electronic components and industrial products; Baidu AiCaiCai provides online transactions, online price inquiries, and a self-operated supermarket; 1688 Industrial Products covers a massive amount of factory sources; JD.com’s Industrial Products warehouse achieves genuine products at low prices with same-day delivery;
Zhongyeda Mall mainly deals in industrial electrical components.
Comprehensive platforms are suitable for price comparison and small to medium batch procurement.
V. Choosing the Right Platform by Category
Choose a platform based on category and scenario.
Based on procurement experience, standard machined parts and profiles are sourced from FA platforms such as Yiheda and Misumi; pneumatic and hydraulic parts are sourced from authorized channels of SMC and Airtac or automation malls; spare parts are sourced from Zhenkunxing and JD Industrial; electronic components are sourced from RS and Digikey; and non-standard customized parts are sourced from 1688 and Aihefa OEM.
Choosing the right platform ensures timely delivery, cost savings, and after-sales service.
Conclusion
What are some good platforms for supplying parts to automation equipment?
The core is a “three-tiered matching”: FA (Factory Automation) platforms manage design selection and standard parts; MRO (Maintenance, Repair, and Overhaul) platforms manage spare parts and centralized procurement for cost reduction; and branded marketplaces and comprehensive B2B platforms manage electrical components and supplementary categories—these three elements combine to form a closed-loop supply chain from drawings to spare parts. No single platform is a panacea;
only a combination of strategies—choosing the right platform by category, delivery time, and budget—can ensure fast and cost-effective procurement.
