The bearing international standard stage adds "Luoyang wisdom"
The reporter learned from Luoyang Bearing Research Institute Co., Ltd. that the international standard proposal ISO/NP 25260 "Rolling bearings-Insert bearing units" (Rolling bearings-Insert bearing units) led by it in the field of rolling bearings has been officially established recently to improve China's bearing industry. Contribution to industrial international competitiveness.
As the fifth international standard proposal proposed and approved by my country in the field of rolling bearings, and since China assumed the secretariat of ISO/TC4/SC6 (International Organization for Standardization/Rolling Bearing Technical Committee/Outer Spherical Bearings), this sub-technical committee is the first The proposal for successful project establishment, ISO/NP 25260, was led by the Shaft Research Institute, and Dongguan TR Bearing Co., Ltd., Panke Bearing Group Co., Ltd., SKF (China) Co., Ltd. and other units participated in the development. It was proposed based on my country's relevant national standards. Specifies the types and combinations, overall dimensions and technical requirements of seated insert spherical ball bearings.
This international standard proposal was initially discussed at the ISO/TC4/SC6 annual meeting in May 2023, attracting the attention of relevant countries. Afterwards, it went through stages of draft preparation, communication with relevant countries and enterprises, and voting, and was finally approved by Germany and Japan in recent days. , Austria, France, Russia and other countries supported, and the project was officially established.
The seated spherical ball bearing is composed of an spherical ball bearing with seals on both sides and a cast (or steel plate stamped) bearing seat. It has the advantages of compact structure, perfect sealing, convenient loading and unloading, and large automatic adjustment range. It is used in mining , metallurgy, agriculture and other fields have been widely used. my country is an important producer of seated spherical ball bearings. my country's leadership in developing its international standards will continue to enhance my country's influence and voice in this product field and help protect the rights and interests of domestically produced bearings in international trade.
In recent years, as the leading unit of ISO/NP 25260 and the unit responsible for the ISO/TC4/SC6 secretariat, the Shaft Research Institute has always adhered to its original mission and successfully participated in the formulation and revision of a number of international standards for rolling bearings. In the future, the unit will strictly follow ISO work processes and requirements, grasp the timing of international standard projects, organize domestic and foreign experts to jointly promote the drafting of ISO/NP 25260, and strive to achieve more breakthroughs in the field of international standards work.
