上海微型轴承厂是一个生产为精密仪器仪表配套用,孔径9 m/m以下微型轴承的专业工厂。1960年建厂初期,广大职工艰苦奋斗、自力更生造出了“争气牌”微型轴承,填补了国家空白。二十年来,上微厂产品的品种从原有15种、迅速扩大到40多个系列,700多个品种,产量平均每年以14.85%的递增率持续增长,由1960年的16万套,激增到1980年 Shanghai Miniature Bearing Factory is a professional factory for the production of precision instruments and meters, miniature bearings with an aperture of 9 m/m or less. In the early stage of the establishment of the factory in 1960, the majority of employees worked hard and made self-reliance to create a “competition brand” miniature bearing, which filled the country’s gaps.
