ball bearings

[Efa]

I hope I have chosen the right forum (it is the first message I write).
how are ball bearings mounted? That is, having separate spheres and cage rings, how are they put together? heats up the external disk and cools the inner one so you can stick the cage with the balls?
Thank you.

the forum is correct but lacks a fundamental rule to respect: besides reading and studying the rules of the forum, a minimum of presentation is there.

on the question ... I think I do not stall them (for tolerance issues). I don't want to have said a beaver!

put the inner ring inside the outer one and then move it all out of center (put the two rings in tangency). in the space that remains you insert the spheres into the correct number and then the gaps so that the inner ring leads back to the center. At that point, insert the cage that will keep your spheres equi-detached, and as a consequence you will have that the inner ring will no longer move from the center.
this for standard bearings, then there are cases where the balls are too many to do this game, and then it is correct by inserting a notch on the outer ring from which to pass the spheres.

I apologize for not being introduced; are stefano (efa for friends) 22 years, student of mechanical ing at bergamo university. congratulations to the creators of this site.

Thanks for the answers, I just didn't understand what you mean by "tach", is a hole on the outer ring? Does the same process also apply to roller bearings?
thanks again and good day.

there is a beautiful video on youtube showing industrial bearing mounting

the notch in question is nothing but a milling in the inner edge to the wire of the track.
for rollers the speech is the same if they have the orletti both rings, but they are special cases. Usually just put the reels in place on the outer ring and thread the inner ring, which is nothing but a bushing. in fact often use roller bearings rather than ball bearings simplifies assembly of the machine.
If you go to the site, which I know, of the skf or of the inine find all the examples of this world

Hi.

doubt clarified, thank you. In fact, it seemed strange to me that such precise objects were dilated hot and cold, not counting the cost of the process. I have to say, however, that wandering the internet I have found many more who support that argument. Thank you.

apart from that to impose the expansion necessary to pass the spheres if you do not get to the melting point little we miss...
