These tolerances follow ISO standards, but some countries use different names for them. (These JIS standards are based on ISO standards.)īearing tolerances are standardized by classifying bearings into the following six classes (accuracy in tolerances becomes higher in the order described): 0, 6X, 6, 5, 4 and 2.Ĭlass 0 bearings offer adequate performance for general applications and, bearings of class 5 or higher are required for demanding applications and operating conditions including those described in Table 7-1 High precision bearing applications. These tolerances are prescribed in JIS B 1514-1, JIS B 1514-2, and JIS B 1514-3 (roller bearings - bearing tolerances part 1: radial bearings, part 2: thrust bearings, and part 3: permissible values for chamfer dimensions). Accuracy and roughness of shafts and housingsīearing tolerances and permissible values for the boundary dimensions and running accuracy of bearings are specified.
