At the 138th China Import and Export Fair in 2025, ball bearing makers including WD Bearing Group showed off automated production lines, new materials, and smart-sensor bearings while a USD 7.26 billion 2025 market heads toward USD 12.15 billion by 2032. [S1]
For a specifying engineer, the takeaway is less about a single product and more about the supplier capability envelope being signaled at this fair: automated and AI-assisted bearing production lines, triboelectric-nanogenerator sensors that flag rolling ball defects in service, and manufacturing practices aligned to ISO sustainability standards. If your drawings or supplier audits depend on verified production methods, defect-monitoring features, or documented cost reduction from green manufacturing, this is the kind of event to track for vendor shortlisting, line-walk planning, and follow-up RFQs.

What was shown at the 2025 fair
The 138th China Import and Export Fair in 2025 served as the venue for ball bearing manufacturers to present updated production equipment, materials, and bearing designs. WD Bearing Group was named among the exhibitors, with its supply scope covering OEMs in pumps, electric motors, gearboxes, material handling, agriculture, and construction. Coverage emphasized automated systems and AI-assisted manufacturing tools intended to improve precision, reduce waste, and lower energy use on the shop floor. [S1]
Figures and named items in the article
The article cites a ball bearing segment growth rate of over 6% CAGR from 2023 to 2028, attributing demand to material handling, agriculture, and construction. It also cites a market projection moving from about USD 7.26 billion in 2025 to around USD 12.15 billion by 2032. On sustainability, the piece states that greener manufacturing methods can cut operational costs by 20-30% and references a study from the International Organization for Standardization (ISO) covering such practices; the ISO finding is truncated in the source text and is not quoted in full here.

What it means for the ball bearing category
Two technology threads in the article matter to bearing selection. First, manufacturing-side: AI-driven and automated production lines with new materials aimed at durability, with the stated goal of reducing friction and wear in service. Second, in-service monitoring: bearings described as integrating triboelectric nanogenerators and machine learning to detect rolling ball defects as they occur, enabling earlier intervention. Both threads point to a category where specifying engineers will increasingly need to ask suppliers about production method documentation and any built-in condition-monitoring features, not just basic load-life ratings.

How to verify at the source
The source is a WD Bearings blog post, so treat its market figures and growth claims as promotional. Cross-check the over-6% CAGR and the USD 7.26 billion to USD 12.15 billion projection against an independent industry analyst, and pull the full ISO study on greener manufacturing cost reductions directly from iso.org rather than from the blog summary, which is cut off mid-sentence. For vendor evaluation, request WD Bearing Group's production-process documentation and any available data sheets on the triboelectric-nanogenerator bearing sensors before incorporating them into a spec.
