BEIJING — July 21, 2026 — On the morning of July 21, the National Technical Committee for Standardization on Rolling Bearing (hereinafter referred to as the "Committee") hosted the 2026 National Standard Review Meeting for Rolling Bearings via video conference. The meeting reviewed the submission drafts for two key national standards:
1. Rolling Bearings — Sleeve-type Linear Ball Bearings — Boundary Dimensions and Tolerances
2. Rolling Bearings — Ceramic Rolling Elements — Terminology and Characteristics of Surface Defects
A total of 66 committee members (including 3 representatives) attended the meeting, accounting for 98.5% of the total 67 eligible members.
Key Highlights & Opening Remarks
The meeting commenced with an opening address by Jiang Wei, Chairman of the Committee and Chairman of Sinomach Precision Industry Group Co., Ltd.
In his speech, Chairman Jiang outlined the latest directives from the Standardization Administration of the People's Republic of China (SAC) regarding the acceleration of standard revision processes and the stringent control of drafting quality. He articulated two major operational requirements for the Committee's future initiatives:
• Enforce Strict Review Controls: Solidify the bedrock of standardization by ensuring the highest quality in standard approvals.
• Consolidate Foundational Work: Build industry-wide consensus to foster collaborative strength in standardization efforts.
Standard Review and Approval
During the technical review session, panel experts received detailed presentations from the drafting units regarding the formulation process and core technical parameters. Following an item-by-item examination of each chapter and clause, both national standards successfully passed the final review.
Industry Impact
The two newly approved national standards target critical domain applications—specifically sleeve-type linear bearings and surface defect terminology for ceramic rolling elements. Once implemented, these standards will serve as essential foundational benchmarks, driving high-end innovation and precision engineering across the rolling bearing industry.
