Still working so far. Bearings are sticky. Some almost began to bind, but working with them on the pole you can get rid of the stickiness, but unfortunately not for everyone. Haven't finished the project (banner printer) yet, but haven't noticed why (this) part failed. I hope those aren't the famous last words. At first glance all the bars appear to be straight and the bindings appear to be the same, but I have to tighten them to the maximum to somehow secure them in place. How to almost break a hex key. Ultimately they seem perfectly capable of getting the job done, but it's also not a rocket engine so they can improve tolerances and quality control.
