Hi Buster,
You could use the Scaleauto SC-1329 flanged ball bearings 3/32 x 6mm. However not very cheap!
Beware if you order them then it is possible that these bearings are wrongly packaged with a wrong number (SC-1324). Like mine!
There are other sources too.
In the left you see the 3/32" bearing:

Here I have them applied too. With the usual NSR, Slot.it etcetera stuff.:
