Bearing Tolerances Precision ClassBearings Direct

Bearing Tolerances Precision Standardized bearing tolerancing is vital within all industries so that users know what they are purchasing Trusted bearing manufacturers state a tolerance and customers know exactly what they are receiving This enables swift engineering design analysis etc

Basic bearing designation system SKF

03 = 17 mm For bearings with a bore diameter < 10 mm or ≥ 500 mm the bore diameter is generally given in millimetres uncoded The size identification is separated from the rest of the bearing designation by an oblique stroke e g 618/8 d = 8 mm or 511/530 d = 530 mm

HOW TO UNDERSTAND BEARING NUMBERSMechanical

For example bearing 6303 will have bore diameter 17 mm If bearing will have a bearing number with last two digits 04 or more than 04 in this case bearing bore diameter could be easily calculated by multiplying the last two digits with 5 and result will be considered in mm For example if we have a bearing 6205 it bore diameter will be 25 mm
