    HI Alan, here is a link explaining ABEC tolerance:

    http://www.mcmaster.com/library/20070314/60355KAC.pdf

    You will notice that on the shaft diameter difference is .0001"(one ten thousandth of an inch). For the O.D. (outside diameter) the difference is .0001" to .0002". So you are looking at a difference of .0003" total deviation. In my world, thats a lot. In a reel that is more than likely plastic molded to a tolerance of +/-.010", at best, or machined to a tolerance of +/-.005", the price difference isn't worth it. More important is the quality of bearings! Just my two cents.....
