You want a bearing that works right when it comes off your printer. This caged ball bearing prints as one piece and spins smoothly without extra work. The balls sit in a cage that lets them roll freely, and small shafts keep each ball locked in place while printing.

The design gives you three clearance choices. Pick .000 inches for a tight fit that needs a little break in time, or choose .0025 or .005 inches for bearings that spin right away. Since the balls and races touch at small points, even tiny clearance spaces make a big difference.

Use this bearing in robots, mechanical projects, or anything with moving parts. It spins surprisingly well and gives your creations smooth, working motion from day one.
