Slightly more complicated (yet much more realistic) way to build a retainer cage <link>.
To build this model, i assumed, that:
- bearing inner diameter = 20 mm;
- bearing outer diameter = 40 mm;
- ball diameter = 6 mm;
- # of balls = 8;
- thickness of the retainer = 0.5 mm.
Besides, i decided to make it a multi-body part, but surely, it can be made like an assembly.
Also, the model is built with zero tolerances and without "cosmetic" elements (like fillets, chamfers, etc.), that should definitely present in real detail.
So, here is the procedure:

Look in LIBRARY of some already constructed ball bearing, download it and look how it was done.

you should use circular pattern for this application

Create a path of the balls, then cut a diameter of balls (plus a gap) along the path. I haven't tried it, but it should work.

Unfortunately, some pictures in the tutorial were auto-shrinked improperly while submitting :( And I don't know, how to replace them. Sorry...

Loki - All people have to do is go to the "View" menu in their browser like I.E. and then increase the "Zoom" and make the browser work for them...
