Recently, China led the rolling bearing field international standard proposal ISO/NP 25260 ‘rolling bearings with seat external spherical ball bearings’ (Rolling bearings-Insert bearing units) in ISO/TC 4/SC 6 ‘external spherical bearings’ sub-technical committee formally established. The proposal of ISO NP 25260 ‘Rolling bearings-Insert bearing units’ was formally established in ISO/TC 4/SC 6 ‘External Spherical Bearings’.
ISO/NP 25260 is led by Luoyang Bearing Research Institute Co., Ltd (hereinafter referred to as Axis Research Institute), with the participation of Dongguan TR Bearing Co., Ltd, Pan Tech Bearing Group Co.
The international standard proposal is in China to assume the secretariat of ISO/TC 4/SC6, the sub-technical committee of the first successful project proposal, the proposal will make the work of ISO/TC 4/SC 6 more active.
This proposal is also the fifth international standard proposal that China has proposed and approved in the field of rolling bearings, which marks the continuous and rapid development of the international standardisation of rolling bearings in China.
ISO/NP 25260 based on China’s national standard GB/T 7810-2017 ‘rolling bearings with seat external spherical ball bearings dimensions’, GB/T 27555-2011 ‘rolling bearings with seat external spherical ball bearings technical conditions’ and put forward, intends to provide for the types and combinations of external spherical ball bearings with seat, dimensions and technical requirements.
This international standard proposal was initially discussed at the annual meeting of ISO/TC 4/SC 6 in May 2023, which attracted the attention of relevant countries;
Later, after the draft preparation, communication with relevant countries and enterprises, after one year, a three-month proposal ballot for new work items was formally launched on 20 May 2024, which was supported by Germany, Japan, Austria, France, Russia and other countries, and was formally established on 26 August.
China as an important producer of the seated external spherical ball bearings, China led the development of the international standard for seated external spherical ball bearings, marking China’s influence in the field of the product and the right to speak is increasing, and help to protect the rights and interests of China’s such products in the international trade.
As the lead unit of ISO/NP 25260 and the secretariat unit of ISO/TC 4/SC 6, Shaft Research Institute will strictly follow the workflow and requirements of ISO, grasp the time node of international standard project, and organise the domestic and foreign experts to promote the drafting work of ISO/NP 25260, and contribute China’s power to international standardisation in the field of rolling bearings.
