PN Racing Steel Ball Bearing Set (7pcs)
[600129]

I like these bearings. They are great once you clean the shipping grease out of them. The best results I had where to put it glass container and spray with motor spray or other grease cleaner and let soak for 10 minutes or so, then blow them out with compressed air. Repeat if needed. Test spon on a pencil or screw driver and make sure they spin free. I like to leave them dry for maximum spin but a half drop of bearing oil should make the last longer.
