On December 14, 2020, the National Standardization Administration of the People’s Republic of China approved and issued the English version of 172 national standards. Among them, there are three in the field of rolling bearings, respectively GB/T32325-2015 Rolling bearings - Specifications for vibration (velocity) of deep groove ball bearings, GB/T32333-2015 Rolling bearings - Measuring methods and specifications for vibration (acceleration), GB/T 33624－2017 Rolling bearings - Test and assessment methods for cleanliness. And these three standards are also the first English versions of national standards in the field of rolling bearings.

These three rolling bearing standards are based on the research results of the 2012 Industry Research Project "Research on Key Common Technical Standards for Rolling Bearings" of the General Administration of Quality Supervision, Inspection and Quarantine, and they are high-level national standards supported by experimental research results.

GB/T32325-2015 Rolling bearings-Specifications for vibration (velocity) of deep groove ball bearings specifies the technical requirements, measurement and evaluation methods and inspection rules for the vibration (velocity) of deep groove ball bearings in the diameter series 0, 2, and 3 deep groove ball bearings with a nominal outer diameter of 10mm～200mm and an external dimension in accordance with GB/T 276. GB/T32333-2015 Rolling bearings-Measuring methods and specifications for vibration (acceleration) specifies the vibration (acceleration) measurement method of rolling bearings and the technical conditions for vibration (acceleration) of deep groove ball bearings. GB/T 33624－2017 Rolling bearings-Test and assessment methods for cleanliness specifies the cleanliness measurement and evaluation methods of rolling bearings and bearing parts, including particle counting method and weighing method, which fills the technical gap in the bearing industry.

Bearings are important basic components in the manufacturing industry, and high-quality bearings are an important foundation for promoting international cooperation in production capacity and equipment manufacturing. The publication of the English version of the national standard will enhance the international influence of China's bearing standards and lay a solid foundation for further international standardization work.
