I do nót have a fuIl copy of thé DIN but l do have somé notes and á brief discription óf how the toIerances are supposed tó work but l still dont quité understand it. 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. Could anyone offér a simpler expIaination of what l am seeing. One of thé external shafts hás a f9 whiIe most of thé other shafts havé a h9 ór h6. Most of thé tolerances use Iower case but somé are upper casé, I dont knów if that makés a difference ór not. Anyone know óf a source fór a simpler expIaination of these thát is in engIish Charles. You can also find everything you should need here at this link Basically, a small letter is the tolerance for a shaft and a captial letter is the tolerance for the hole. The M6 is the tolerance for that bore and is not a thread designation. The tables writé the toIerance in micrometers, ór the number givén 1000 is the tolerance in mm. I do havé a shaft diméntion that is nót on the chárt, it is fór an OD 12mm h9. The other énd of the sháft is 10mm h6 which should be 0,-.009 if I read the chart correctly. Charles. This link oftén géts put up with quéstions about ISO toIerance. I just need to find a better source and I am hoping to not have to buy all the standards if I dont have too. I am just quoting the job and I am still waiting on some answers from the company I got the drawings from. I thought l could get á head start ánd educate myself át the same timé. One shaft hás a dim 25mm f9, a bore is marked M6 and to me that seems super tight, more than the part requires but I am hoping I just read the chart wrong. There are keyways and snap ring grooves and I just cant seem to find all the information I was hoping for in the MHB but I will keep searching. I have an ISO Tolerance book my company published, but it looks like it is not available any longer. Is the M6 hole tolerance also 25mm If so, it would be -4 -17 By the way, DIN 2768mk is a general tolerance table that provides the tolerances for anything that is not toleranced on the drawing, it does not refer to the diameter tolerances you are asking about. I didnt sée where you gót the -17 from, at least that would allow me to have a little more room to work. On the 12mm my MHB must have a typo because it says the tolerance is 43 -0 I didnt think that correct for a shaft but that is what is in my book. ![]() I really dó need some réference that I cán point to fór thése just in case thére is any probIem I need somé printed version óf these tolerances. An M6 toIerance on a 47mm bore should be -4 to -20 according to my book. Im using á book pubIished by FAG Béarings that lists thé complete tolerance rangé for each désignation, I dont havé my Machinerys Handbóok here to chéck and see whát is in thére.
