Angular contact bearings

Has anyone tried using angular contact bearings for the ends of the worm gear in a CGEM? I heard some discussion a while back and was interested in maybe giving them a shot. I have noticed that there is a tiny bit of lateral play in all of the different standard type bearings I have tried. Finding the right balance between tight enough and too tight has been a bit of a challenge at times.

I found these listed at vbx.com and was wondering if these might work:

I guess I am just getting bored with all of the cloudy weather lately. I keep finding myself looking for excuses to fiddle with the mount.

Thanks,

Chris

I ordered those exact bearings for my ieq45 expecting to see a noticable difference. I did not notice any difference with regular bearings, the fine line between tight enough and too tight seemed the same to me, I would save your money.

I've just been playing with some angular contact bearings for this purpose recently. So far, I'm not convinced that they do any better than properly adjusted standard bearings so I'm dissapointed. They seem to be just as difficult to adjust and no less prone to play in this application. When it comes down to it, the problem we have here is very slow movement on bearings that are capable of very high rpm. Were this a high rpm system, I expect that the difference would be more noticeable, but I think that in this application there is more to be gained from using good high quality ceramic balls in a standard bearings than in using angular contact bearings.

Much appreciated. Too bad they did not work out.

Thanks,

Chris
