Bearing Tolerances
Allowable rolling bearing tolerances have been established according to precision classes. Bearing precision is stipulated as JIS class 6, class 5, class 4, or class 2, with precision rising from ordinary precision indicated by class 0. Table 6.1 indicates which standards and precision classes are applicable to the major bearing types. Table
