Atom 500 / 550 Bearing Guide

[SamCassidy]

Was missing a few bearings and nobody seemed to have a comprehensive list of all needed Atom 500 / 550 bearings, so rolled up my sleeves and made one. Hopefully we can get this stickied for future reference incase anybody else needs the list in the future.

+1 yes they do. except for those flybar bearings (which i didn't think was needed any more), the thrust bearings, and one way bearing (forgot to add these) but they can be added if you email them.

Thank you! I have been looking for this one for a few days! Can you say anything ceramic vs. steel wise on the Boca's? I have had very good experiences with their bearings in the past.

This kit does have the two radial bearings for the autorotation / one way assembly, correct?

[tony521]

Hey Sam, yes the kit does have the radial bearings for the one way bearing, i just had them change it to a 3mm thick vice the 4mm. the only thing that's missing is what i had mentioned earlier. I personally have been using the steel bearings, and they are working great.

Just got my kit from BOCA. Highly recommended. Came in 3 days, packaged very well.
