1. Great to hear! I hope you enjoy them like I did. They were noticably more uniform than my quartz or boro beads and the airflow was smoother.oooh. im getting some. nice find!
some concerns about the dust online but in this usage a non issue i think.
2. My understanding is that they wouldn't dust under our usage because they are designed to be used in car bearings (constant motion and rubbing while staying smooth). A bearing that readily dusted wouldn't last a long time. Rubies are slightly harder than Si3N4 and would produce the slightest bit more dust, if anything and these bearings are cartoonishly durable.

Edit: I was doing some more googling and the bearings have a higher molar mass vs corundum (140 v 101 g/mol); and boro glass is higher at both at 180 g/mol.
