Industry Overview: The Dominant Trend of Domestic Substitution in Industrial Consumables
Industrial consumables refer to industrial products consumed during daily factory operations, such as cutting tools, bearings, seals, hydraulics, fasteners, welding materials, lubricants, abrasives, occupational safety gear, and hardware tools.
Key sector data (China Machine Tool & Industry Association / China Tungsten Industry Association): In 2023, China’s cutting tool market reached 49.2 billion RMB, with cemented carbide tools accounting for 63%. The share of imported cutting tools dropped from 37.20% in 2015 to approximately 27.20% in 2022; in 2024, the customs import value for cutting tools was 8.525 billion RMB (down 2.66% year-on-year)—highlighting domestic substitution as a long-term, decade-spanning trend.
The global cemented carbide cutting tool market is valued at approximately 20 billion USD, while the Chinese market stands at around 40 billion RMB (data from Warui Precision’s investment research, June 2026).
Bearings: China accounts for over 30% of global bearing output (industryinchina). Seals: China accounts for 30% of global mechanical seal consumption, yet domestic manufacturers hold only about a 4.5% share of the global top 10—indicating the greatest room for growth (Tianxia Factory Industry Research Institute).
Structural Logic: The upgrading of high-end manufacturing (with the CNC adoption rate for machine tools rising from 28% in 2015 to 48% by 2025) is directly driving demand for CNC inserts; meanwhile, sectors such as aerospace, new energy vehicles, and high-end medical equipment are propelling the localization of high-precision consumables—advancing the quality from merely “functional” to “high-performance and durable” (Ouke-Yi Q1 2026 Report, *Shanghai Securities News*, April 24, 2026).

The Top Five CNC Cutting Tool Manufacturers: Spearheading Domestic Substitution
Top five domestic CNC cutting tool manufacturers in the first half of 2026 (Jin Chui New Media, September 23, 2026): First place—Zhuzhou Diamond (a subsidiary of CMC Tungsten): Cutting tool business revenue of RMB 2.606 billion; cutting tool segment grew 53.18% year-on-year; group-wide net profit of RMB 2.076 billion. It is the largest comprehensive supplier of cemented carbide cutting tools in China, holding approximately 25% market share; its products offer a price-performance ratio comparable to European and American brands; and it undertakes strategic machining tasks—such as processing special steel decks for aircraft carriers and titanium alloys for large aircraft—serving as a heavy-duty pillar safeguarding the nation’s industrial capabilities (leading the “Three Musketeers” of Zhuzhou cutting tools).
Second place—Ouke-Yi: Revenue of RMB 1.207 billion; net profit attributable to the parent company of RMB 622 million; ranked first domestically in saw blade production scale (National Manufacturing Single-Item Champion, China Tungsten Industry Association); rapid growth in M-class (stainless steel) and P-class (steel) CNC inserts as well as the “Economic King” series face mills; and a multiple-time winner of the Golden Blade Award and Ringier Technology Innovation Award.
Ranked third is Huarui Precision (688059): Revenue of RMB 621 million (+19.70%) and net profit attributable to the parent company of RMB 238 million (+178.32%). Annual production of cemented carbide CNC inserts exceeds 100 million units, ranking third domestically in 2024 (per the China Tungsten Industry Association). Full-year 2025 revenue surpassed RMB 1 billion, with a gross margin exceeding 40%, a net margin of 18.66%, and operating cash flow of RMB 280 million (1.5 times the net profit). Product performance reaches 85–90% of top-tier European, American, and Japanese brands, while prices are only one-third to one-half of theirs—making cost-performance-driven substitution the core growth driver (In-depth investment research, June 22, 2026).
Ranked fourth is Worldia: Revenue of RMB 417 million (+24.54%) and net profit attributable to the parent company of RMB 59 million (+36.03%); the company focuses on PCD/CBN superhard cutting tools, specializing in high-hardness materials.
Ranked fifth is Hengfeng Tools: Revenue of RMB 384 million (+13.64%) and net profit attributable to the parent company of RMB 107 million (+41.33%).
Additionally, Xiamen Golden Egret (GESAC) is a global leader in tungsten powder, with outstanding performance in aerospace-grade cemented carbide inserts (leveraging its position as a source of tool steel materials). Regarding the domestic substitution thesis (cited from Huarui Precision’s annual report): Cutting tools for aerospace, defense, and automotive engines still rely heavily on imports, while leading domestic players are currently pushing to transition from the second tier to the first tier.
III. Top 10 Bearing Manufacturers: The Joints of Major National Industrial Assets

Seals, Oil Seals, and Special Steel Materials: Hidden Champions
Mechanical Seals (Tianxia Factory Industry Research Institute, June 27, 2026): Global top 10 mechanical seal manufacturers—John Crane (UK) ¥14.4 billion, EagleBurgmann (German-Japanese JV) ¥7.2 billion, Flowserve (US) ¥4.3 billion, AESSEAL (UK) ¥2.6 billion, Cdsii (China) ¥2.6 billion (tied for 5th), Chesterton ¥1.8 billion, Nippon Pillar (China) ¥1.2 billion, Smiths ¥0.9 billion, Ningbo Donglian ¥0.8 billion, Hatebur ¥0.6 billion. Domestic manufacturers hold a combined share of approximately 4.5% of the global top 10, a figure severely disproportionate to China’s 30% share of global consumption. Cdsii (300470.SZ): The undisputed leader in China’s mechanical seal industry; 2025 revenue of approx.
¥2.6 billion, net profit attributable to the parent company of ¥470 million, and a net profit margin of 18%, making it the most profitable company in the domestic sealing sector; Huaxiang Sealing (subsidiary of Huaxiang Shares, 002048): Metal bellows mechanical seals, with a sealing business revenue of approx. ¥500 million in 2025. Oil seals: NOK (China) and SKF (China) dominate the high-end market, while companies like Shanghai Laitu offer cost-effective domestic alternatives.

Leaders in Other Categories and Selection Recommendations
Leaders in other categories (industry consensus + listed company data): Hydraulics—Hengli Hydraulic (601100) leader in cylinders, pumps, and valves; Aidi Precision (603638) leader in hydraulic breakers and components; Fasteners—Jinyi Industry (601002) high-speed rail fasteners and standard parts; Welding materials—Atlantic (600558) leader in welding materials; Hardware tools—GreatStar Industrial (002444) global leader in hand tools (top tier in tool chest/power tool exports); Abrasives—Shengquan Group (605589) resins and casting materials; Baige Abrasives (grinding wheels/diamond abrasives); Lubricants—Longpan Technology (603906), Great Wall Lubricant (Sinopec); Occupational safety—Delta Plus, 3M China authorized channels.
Four key points for selection: First, identify the leaders in specific niches (e.g., cutting tools: Zhuzhou Diamond/Huarui; bearings: ZWZ/C&U; seals: Zhongmi Holdings; hydraulic cylinders: Hengli)—batch consistency among leading products is a crucial factor regarding hidden costs. Second, for bulk consumables (welding materials, lubricants, abrasives), utilize manufacturer-authorized channels or compare prices via MRO platforms (e.g., JD Industrial, ZKH, Xinfangsheng). Third, for technical components (cutting tools, bearings, seals), validate performance through small-batch trials before scaling up (the 6–12 month certification cycle required by major clients acts as a natural market barrier).
Fourth, ensure contracts explicitly stipulate batch traceability, quality documentation (CoC, material specifications, and certificates of conformity accompanying the shipment), and warranty terms—rankings for industrial consumables should be based not merely on scale, but on market position within specific niches and supply stability. Summary: Rankings of Chinese industrial consumable manufacturers—cutting tools: Zhuzhou Diamond/Oky/Huarui Precision/Worldia/Hengfeng; bearings: ZWZ/C&U/LYC/HRB/ZYS; seals: Zhongmi Holdings; specialty steel: CITIC Special Steel/Fushun Special Steel; hydraulics: Hengli/Aidi; fasteners: Jinyi; tools: GreatStar.
Selecting niche leaders, using authorized channels, and verifying batch traceability through small-batch trials is a more reliable approach than relying solely on rankings.
