Bearing Pocket Dimensions

Go to your bearing manufacturer's website and look at the tables for your bearing.

Things like materials, environmental and required tolerances for those conditions will determine your tolerances.

There's also the option of an undersized pocket that gets heated and fitted with a cold bearing to attain the required retention.

Contact your bearing maker, otherwise you are taking a chance on premature failure.

It's a McMaster bearing. Don't think you can get too much info.

I guess I'm going to have to try and see.

For further assistance with bearing selection and design, please feel free to contact our engineering team or look at our online catalog .

The following tables are a guide for establishing shaft and bearing fits for miniature and instrument bearings when the expansion coefficients of the shaft and housing are similar or when the operating temperature differential between them is nominal. In other conditions, modification in fits and internal clearance may be required.

* For closer running accuracy or reduced axial play K13 internal clearance may be used provided that the fit of the outer ring is line to line or looser

** For closer running accuracy or reduced axial play K25 internal clearance may be used provided that the fit of the outer ring in the housing is line to line or looser.

If you are going to continue to do any machining work, buy this:

Machinery Handbook

It has all those answers you need to have handy. I got my MH edition in 1966 when I started my apprenticeship and will probably be buried with it.

PS - I don't have an affiliation with Amazon for pushing this book.

All of my first programs solved formulas from the 18th edition of the MH bible. The last one (for that machine) solved for the volume of an ellipsoid given three perpendicular axises relative to the the major and minor dimensions of the ellipsoid.

I wrote it in assembly language to fit nicely into the 2k of memory the machine had in 1977. I was 13!

I have that edition on my Christmas list. The one I used was my dad's and nobody knows where it went.

Thank you all of you guys, I'm still doing some reading about bearings. I'm not in a rush to do this so I can take some time.

I'll post again if need more advice.

1.1255. look up TPD. Also it depends on the bearing temperature and material expansions at temperature.

You have to determine the type of fit you need.

Don't use the Machinery's Handbook for fits and tolerances, use the bearing manufacturers, you can get this information from the bearing manufacturer, SKF for example.

Now if your on a project,.. school, personal or for work. You'll need to know and understand the type of fits from the bearing manufacturer that you require, at first look, its a little difficult to read but you get adjusted after awhile.
