为配合各轴承厂提高产品质量,我所将一机部（72）汽字029号文重申的有关滚动轴承专业标准部分再版付印,预计十一月底发行。本标准适合轴承生产使用,希望需要单位从速向我所资料室购买。 In order to improve the product quality of each bearing factory, we will reprint the professional standards of the rolling bearing that are reiterated by the Ministry of Machinery (72) Steamword No. 029, which is expected to be issued by the end of November. This standard is suitable for the production of bearings and it is hoped that the unit will need to purchase it from our reference room as soon as possible.
