The 2" bearing that is part of the RB-157 is custom made and not available individually. https://www.infinitytools.com/rb-157-... As far as your specific application is concerned, using the bearing on a smaller diameter bit instead of a larger should not be a problem whatsoever. Just be mindful of impact to the bearing from the side.
