Because of that, the rest of the bearing is sticking through the tube wall .15" into the tube, taking up more space than the shaft collar.

If you remove the collars from the inside you could replace them with a spacer so that the bearings (with their flanges on the inside) are flush against spacer or gear. Make the spacer long enough so that it presses against the gear and the gear presses against the other bearing. Doing that, you would only need a bolt/washer combo to retain the shaft axially if it isn't already held stationary by something else.
