Abstract
In this paper, we researched the accurate examination of two methods regulated by Japanese Industrial Standard for rotational accuracy of Rolling Bearings. We produced two measuring apparatus based on JIS and measured radial accuracy of angular contact ball bearing in various conditions. The results are summarized as follows: (1)The evaluation method in JIS had large dispersion. (2)The influence of the measuring conditions on radial run-out was very big. It was necessary for unify the measuring conditions in order to evaluate the radial accuracy of rolling bearings. (3)Comparing results of two methods, accuracy of method 2 is better than that of method 1.
