The BA123 casters have a rubber lining on either side of the caster;
I had the same deterioration on my BA123's. . . except I didn't find
out
until I had rolled one over a section of carpet in the house.
(That was fun to clean up. . . . not !)
Presumably, the rubber is for vibration deadening.
Since I didn't have a convenient source for them at the time,
I opted to make them less messy.
I just took a small flat-blade screwdriver,
and cored the rubber out from both sides
of each caster. Since it was already "leaking" out
from all of the casters, I didn't have any
"moral" issues with this.
Once the rubber is out, the casters are just plain ol' casters,
and they roll just fine.
More recently, additional research has revealed:
The casters were made by Shepherd casters (www.shepherdcasters.com).
I found a close replacement part -
Shepherd PSF50101BK has the same mounting pattern, and diameter.
Although it is a slightly different style, it should make an adequate
replacement.
A quick search turned up this:

As info. . .

I was lucky, both of my BA123's have had their wheels die while in
storage. Not so lucky for the storage company. :-)

I've already significantly deadened the noise on the one I use by a
combination of getting all the side panels, AND switching to 3.5"x1"
SCSI drives.

With everything that is going on with moving into our new house,
somehow I think this makes the most sense. Besides I haven't even
figured out where the Q-Bus boards and drives are! :-) Still at some
point I'll most likely want to bring it into my office, unless I
simply leave it out in the garage.
