A:The product pictures correspond to the article group. Due to the large number of articles, the individual photo of each article cannot be made available. In concrete terms this means that deviations in size, color or geometry are possible. We always strive to select an image that comes as close as possible to the real article.

A:Some simple guidelines are:
Generally metric bearings will have full mm dimensions. Thus 20mm bore x 47mm outside diameter x 14mm width = 6204 series metric bearing.
Imperial bearings measured in metric will not have full mm sizes. Thus 12.7mm bore x 28.57mm x 7.87mm is really 1/2 inch x 1-1/8 inch x 5/16 inch = KLNJ1/2 series imperial bearing.
There are a number of unit converters available to go from metric to imperial and vica versa.
