VXB 608 Full Ceramic Skate Bearing White Ceramic ZrO2 Rings with Si3N4 Black Balls 8x22x7 Ball Bearings VXB Brand

Excellent bearing for spinners. Bearing spins for about 20 seconds with nothing attached to it. If you attach a weighted spinner around it, you should be able to do 2-8 minutes with it (depends on the design of the spinner [wind drag] and its weight). I've had previously used cheap 608 metal bearings and this ceramic bearing is a significant improvement. Yes, you read that correct, I've gotten 8 1/2 minute spin times from this bearing with a spinner that has a decent amount of heft to it. Note: Do NOT add lubrication, even thin oils will slow it. The ceramic bearings don't need lube. Also, before you pass judgement on the bearing, try breaking it in first by installing a spinner on it and then positioning it so a fan blows across the spinner (to keep it spinning). Let it spin overnight and test it in the morning. You might want to flip the spinner over and spin in the other direction too.

If your bearing gets stuck or runs slow it's probably the little plastic piece that holds the balls in place (see photo) it's very thin and can bend at the part opposite the opening. I think this piece is actually 3d printed which is crazy considering how accurately this piece would need to be created for every bearing. Other bearings have even thinner middle pieces so if there is variation in manufacturing it can easily sort itself out. I replaced said piece even though I didn't have any issues since the slightest material expansion could seize the bearing entirely. This is not acceptable for a bearing at this price point. I will change review if there is a product revision. Otherwise the bearing is very good with my fix and will be keeping it. It spins for an extremely long time.

I have never even seen a bearing worse than this. It barely spins at all and it grinds like nobodys business. I have steel bearing that barely cost 70 cents a pop that spin better.

I tested this against another full ceramic bearing that was all white. I also tested this against a hybrid bearing. This one spins the longest and the fastest in my fidget spinner. It's well worth the $10 upgrade. I'll add pictures and maybe a video later. HIGHLY recommend this bearing as a replacement center bearing.

The first one I got works great. I get a over a 3 min spin time on my figit spinner and don't have to worry about rusting. I ordered 2 more once I receive them and test them out will give an update.

bought as upgrade to the hybrid bearings i have...does not spin longer....

Fairly average spin time of about 2 minutes. Did significantly better with the WRM Bearings 608 bearings but they cost 15 which is 5 more. S

This bearing is nice. It seems perfect for low-load applications like fidget spinners. The bearing spins probably 30 seconds by itself. It spins much longer in an unweighted spinner, probably a full minute. If you hold our all-plastic spinner vertically, you can see the heaviest part rotate to the bottom, so yeah, it is low friction. But is it ten times the bearing that the Toyoosky (ridiculous names for all of these small manufacturers) ceramic is? Probably not. So I guess five stars for performance, but two for value. VXB makes another full ceramic bearing that sells on amazon for a little less than $6, but I haven't tried it.
