recently got one of those full ceramic zr03 black bearings. when it arrived it barely moved. clean and seemed ok. until I did a sleep test, hard straight throw no tricks barely lasted 1 min. when I add tricks and such it gets even shorter.
anyone have experience or insight? anything is appreciated thanks
I have a white ceramic bearing. Was bad until it was not, just needed to be broken in I think. So I threw sleepers for like 10 minutes and it started to spin longer.
Acetone for stainless steel, because you’d have to worry about rust with anything with water in it.
Since you don’t have to worry about rust with the full ceramic, you can use soapy water.
You’ll still want to make sure it’s completely dry before popping it back on the yoyo.
