Right. But even when they fail, the spalling may not spread around. If the
load on these "points" is very high, they may not spall at all: the points
will just displace plastically, or fracture off from local overload. Then
some of the preload is relieved; the bearing runs loose; but the mean load
on the bearings is reduced....

Are you suggesting that lower grade bearing components have less
stringent heat treatment?
