When I built my JGRO I had the same problem. My solution was very low tech and a bit clumsy but it works. As long as the bearing is not too far from the pipe, loosen the bolt that holds the angle aluminium to the mdf and put a small spacer under the end of the Aluminium angle which holds the guilty bearing, once you get it touching tighten the bolt up a bit and check to see that the bearing is still touching the pipe.
