Apsung 6 x17x6mm 606 Hybrid Ceramic Si3N4 Ball Bearings, High Speed Replacement Bearing for Hand Spinner Fidget Toy DIY Packaged With a Gift Case

I have a couple of reasonably heavy brass copper colored metal spinners. Over time and much use, using an air compressor to make these things squeal, my bearings began to fail. I took a chance with this replacement ceramic bearing and could not be happier. I gave it a pretty brisk spin just using my finger to flick it. (Hurts because of the weight) Well I started the timer and it spun for over 7 minutes. It just would not stop. Not a bad improvement, coming from 45 seconds to over 7 minutes was a huge will. The bearing came with a little zippered case that was a nice touch. Very happy.

I purchased this too replace bearings that went bad in my spinner. The spinner was grinding and vibrating. The bearings came in the same case as the spinner did except it has a foam cutout made for the bearings and the little tool needed to open the housing for the bearing. Long story short, it's perfect and I've gained an extra minute of spin time!

This Apsung 6 x17x6mm 606 Hybrid Ceramic Si3N4 Ball Bearings, High Speed Replacement Bearing for Hand Spinner Fidget Toy DIY Packaged With a Gift Case was never delivered. Failure undiscovered until inventory. Probably no recourse. Written off as small loss. Never again w/Apsung.

Better performance than the cageless bearing my spinner came with, much more stable, less vibration, and a longer spin time as well. Had a slight error with the product when it arrived but the customer service was kind to offer a refund and allow for me to reorder the item from the amazon warehouse instead of theirs (2-day shipping vs 20-day respectively). Glad I bought this product!

I used this to replace the bearing that came in a Stylrtop 11T jockey wheel in order to make a fidget. Wow, what a huge difference! This thing now spins forever. I'm really impressed! I will definitely buy more!

Got this to upgrade a spinner... and man did this bearing disappoint! Too much play in the bearing and spins with a grinding vibration even after breaking it in. However, the seller went out of their way to try to fix it.... so 4 stars

Your browser does not support HTML5 video.  I bought this for a project I saw on the internet. It spins very clean, and does not wobble as much as others. Also it is relatively quite to others I have.

It was not the same size as the original, I had to modify the spinner, but a really nice bearing. The inner ring Od was larger. I should have measured better.
