I should have noted below that Figs 3 and 4 only show a cross section
in the vicinity of one ball in the upper part of a bearing.

Are they cross sections of the upper half one bearing so the length
shaft runs parallel to page?

No. Figs. 3 and 4 are indeed cross sections of the upper half of a
bearing. However, the shaft is just below the inner race, and its
longitudinal direction is toward the reader. The shaft is rotating
clockwise. Its circumference thus is moving in the direction of
the inner race, which is the same direction as shown for the force
F3 in Fig. 4. The outer race is of course stationary. To make the
Figs. more complete I should draw I line under the inner race, and
notate the shaft location below. I'm sure it wouldn't hurt to do a
decent drawing either, but ascii is the only thing that shows up in
the archives, so I post in ascii.
It wouldn't surprise me if you were the only person to make the
effort actually look at the figures, so much thanks for that. If
you have any trouble making sense of them I'll be glad to help
out. I make lots of mistakes, so there could be some problems.
