I guess it is the terminology. But when you grease a wheel bearing you
don't remove the race.

Correct, and you are not replacing the bearing either. You are only
servicing it.


And when you replace a bearing, most sources also caution you to replace
the race.

Yes. Use every thing that comes in the the bearing box. The 2 pieces are
a matched set.

That caution
indicates that the race is separate.

Sometimes they are. 1 of the races is seperate. The inner race is a
permanent part of the bearing assembly. Rear wheel/axel bearings are
often all one piece with both races a permanent part of the bearing
similar to the one that the OP is asking about. It must be pressed off
and on.

So is the
race a part of the bearing or is the cage and rollers the bearing?

Is the piston a part of the engine? Yes the race is a part of the
bearing. Front wheel bearings have, like most bearings, 2 races. One is
permanently attached to the bearing assembly, it rides on the spindle and
the other is press fit into the drum or rotor.


Regardless of the
terminology, the unit to change in a saw is one piece and in a car is two
pieces, so there is a considerable difference between a bearing for a saw
and a bearing for a wheel.

Typically the front wheel bearings on a rear wheel car are 2 piece. Front
wheel cars use 1 piece front wheel bearings. Rear axels on rear wheel
drive cars can have one piece or 2 piece. Rear axels on a front wheel car
are typically 1 piece. Almost always a serviceable bearing is 2 piece and
nonserviceable bearing is 1 piece.


Some rear drives have a "non-serviceable" axle bearing, in that the bearing
outer race & rollers are press fit in the axle housing, but the inner race
is actually the axle surface itself(DAMHIKT). One of Fords better ideas, at
least on their late '80s & 90s F150 P/U trucks. If the bearing goes, it
takes the axle surface too. I guess you could stretch the definition to mean
a "serviceable" bearing as long as the axle is considered the inner race.
