Is this a thrust button and can it be removed?

Birdsong and a lot of the other keyboard warriors have given many of us a ton of misinformation. My suggestion is to call the company you got the axles from and talk to them. These day I try to stay away from yoob toob because of all of the BS that is put out there. Don't get me wrong, there is a good amount of excellent information out the. Just be sure to do your research and make sure someones not blowing smoke.
Contacted Moser regarding axles. Axles will accept the tapered bearing if I decide to take that path. None of this is inexpensive. If I'm spending this kind of money I just want it to be right. This includes the removal or not of the axle shaft thrust spacer. Will let install of green bearings make that decision. If it must be removed I will go back to the tapered bearings. Am not going to remove it now due to mis-information. Found adjuster on DrDiff web site.
