Re: lazy susan type bearing? thrust bearing?

My thinking was that this washer should be the same size as the flange diameter of the radial bearing so I can mount them in a forstner hole and this will hold the washer in place and prevent it from rubbing against the shaft, thereby introducing additional friction and causing shaft wear. I'm expecting to drill a hole with 3 diameters:
* smallest diameter accommodates just the half-inch shaft. Probably 5/8"
* second diameter accommodates flanged bearing O.D of 1.125" and holds it in place
* third diameter [on top] accommodates the flange diameter and the spacer/washer O.D. of 1.25"

May be it's not a big deal if I just get a washer with a nominal 1/2" inner diameter and let it rub around? I was just trying to be precise.

Looking forward to receiving it this afternoon!
