在各种汽车的使用和维修中,经常因为缺少滚动轴承而停工待料,我们在生产实践中总结出了滚动轴承代用的方法,可以使汽车及时修好。一、滚动轴承的尺寸特点和代用原则我国国家标准规定:滚动轴承的代号中,最后两位数字表示轴承内径,倒数第三位表示直径系列,第四位表示轴承类型。经过比较我们就可以发现:同一内径的轴承,随着直径系 In a variety of car use and maintenance, often because of the lack of rolling bearings and stop work to be expected, we conclude in the production practice of rolling bearings alternative ways to make the car repaired in time. First, the rolling bearing size characteristics and the principle of substitution Our national standards: the code of the rolling bearing, the last two digits that the bearing diameter, the third last said diameter series, the fourth bearing type. After a comparison we can find: the same diameter of the bearing, with the diameter of the Department
