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.
