Z Axis bearing spinning

Please take a look at the video and tell me if its normal for a bearing to spin the way this one is. I haven’t seen it do this before. Thanks!


It seems not tight enough. You better adjust eccentric nuts little tighter. It must be turning very hard with fingers.

The bearings in the V wheels are suppose to be a light press fit in the Delrin wheel. Specs call for a 16mm OD bearing to press into a 15,95mm hole in the wheel.
I checked one of mine and the bearing measured out at 15,96mm and the wheel at 15,95mm.

It looks like your wheel is an even looser fit.


Thanks for the advice. Im kinda hesitant to mess with it right now because its working good!
