Roller Bearing Sizes
The indicated decimal size values of roller bearing diameters are nominal values provided by the respective manufacturer. These should be considered as guide values only. Actual values may vary and depend on measurement equipment, room temperature and possible other factors. It is therefore mandatory for the diligent mechanic to recheck every individual roller for actual size to calculate tolerances.
