Well, there I go, shooting my mouth off again, without looking it up. I hadn't
run across this type of bearing.

Assembly of most radial ball bearings is done by putting all the balls touching
on one side of the outer race and then inserting the inner race and moving the
balls to be evenly spaced. then they insert the ball retainer. Now that I think
about it, that technique should work with a double row, whether it is radial
or angular contact, too. the fixtures for holding everything in place while this
is done must be pretty ingenious, though. I REALLY wouldn't want to have
to do this myself by hand!

Glad there are people who can set everybody straight when I spout some wild
guesses.
