If I find some time tomorrow, I will see if I can scan my tables and send them to you. I wish I had a copy of the complete tables I could email you, the following link is mounting and dismounting catalog that has tables in the back, but does not have all of what you are looking for. The parts are shafts and couplings and have to fit bearings so I know some of the tolerances are going to be plus and some are minus. Are you sure you are not looking at H tolerance tables? The capital H is for holes and all of those are 0 to a plus number.Īfter you have used it a bit, these tolerances get easier. Here we introduce ISO 2768 standard (General Tolerances for Linear and Angular Dimensions) and ISO 2768 tolerance chart, also provide a free PDF file of ISO 2768 tolerance for download. DIN ISO 2768 mk tolerances I do not have a full copy of the DIN but I do have some notes and a brief discription of how the tolerances are supposed to work but I still dont quite understand it. The +43 on the h9 tolerance is definitely wrong, all the h tolerances are +0 and a negative number. I'm using a book published by FAG Bearings that lists the complete tolerance range for each designation, I don't have my Machinerys Handbook here to check and see what is in there. Bearing tolerances are usually fairly tight since that controls the amount of internal clearance of the rolling elements to the race of the bearing when installed.Īn M6 tolerance on a 47mm bore should be -4 to -20 according to my book.
