Sure there are. I made a 4" dia low speed ball bearing for a project a
few years ago. Used 1/8" balls, and had an inside diameter of 3.25" Be
aware that clamping the races in a chuck will distort them, causing
uneven drag when finished. I doubt you can make a good, high speed, high
load ball bearing on a lathe.

It can be done with rather good sucess..but you use pot collets rather
than jaw type chucks

Hi,
I was wondering if it's possible to make your own bearing channels?
I have two applications where mcmastercarr does not have what I need.
Are there end mills with semicircular tip profiles to mill channels for
balls of that diameter?



thanks!

"The importance of morality is that people behave themselves even if
nobody's watching. There are not enough cops and laws to replace
personal morality as a means to produce a civilized society. Indeed,
the police and criminal justice system are the last desperate line of
defense for a civilized society. Unfortunately, too many of us see
police, laws and the criminal justice system as society's first line
of defense." --Walter Williams
