Re: [CAD_CAM_EDM_DRO] RE: bearing fits was silly machinist / leadscrews forever

I'd recommend looking in the engineering data furnished by the bearing manufacturer of the brand of bearings you decide to use. That's always the best place to look fiirst.

Chris,

Whole BOOKS are written on bearing clearance/press fits! And don't
even TRY to understand the metric (like H7 h5) classes!) OK. Really
they do make sense, but this is NOT a "short answer" subject.
Spesh'ly with 780 people lookin' on...

So, anyone else care to go first ?

Ballendo

P.S. I'd visit your friend and tell him the particulars. Ask his
advice.
