Any European engineers?
Hey Guys n Gals,
I have a Swiss print that reads: Hole 1.6 H7 diameter Shaft 1.6 h8 diameter Metric of course My machinery handbook does not cover that combination of allowances and tolerances. Can you provide the maximum and minimum for the above dimensions? I’m trying to match up EU instruments with US instruments.

I believe you can get those allowances out of bearing books. Torrington, NSK, SKF, et al. I don't have one in front of me right now.
Sorry the torrington book I have does not go below 3 mm and does not list H8 tolerance for the shaft at all. Google ISO 286-2 Use these net resources at your own risk. Good luck Matt Last edited by Matt_'77_2.7; 02-05-2004 at 02:42 PM.. |

We'll I'm a long way from a European engineer but some of us "Maricans" have to deal with these "communist units" all the time.
From "Machinery's Handbook, 25th edition" ANSI B4.2-1978 R1984 based on ISO system of metric limits and fits: 1.6mm "locational clearance fit" or H7/h6 Hole H7: 1.610/1.600 Shaft h6: 1.600/1.594 Fit: .016/.000 all units are in millimeters Cheers, Jim |

Matt,
Thanks I'll try the link you mentioned. Jim, I have the same edition but couldn't find an exact match. I'll give the EU engineers a chance to pipe in. Thanks, Mike

The ISO 286-2 doesn't cover shafts and holes below 3mm?
Where else should I look?
