You could just use a 1/4" or 5/16" aluminum sleeve and use a 1/4" or 5/16" bearing from McMaster or Boca Bearings. I know 192 used Boca last year for their gearbox gears, but personally I haven't used them.

Thanks for the good info! I'll do some looking around for a needle bearing that will do the job. If I don't find one that fits the bill, I'll probably resort to a brass or IGUS bushing.
