R188 Open Deep Groove Ball Bearing, 1/4" mmx1/2 mmx3/16 mm Fidget Spinner Bearing with Nylon Caged (10 PCS)

Ordered these after seeing someone mention them in a review somewhere else on a fidget spinner- they were discontinued but these weren’t, so i decided to order. BEST DECISION EVER. OMG. QUALITY. my jaw dropped when i spinned for the first time after replacing with these. I couldn’t believe how smooth, quiet and amazing the spin felt. And they can go for a looooong time. It felt like seeing the light of day when you never knew what it looked like. Lol but seriously. The quality for the price is soooo good. Like these are exceptional. Even feel so much more well made then the cheap ones that come in the spinners. I will definitely be buying these again and putting them in all my spinners. They work so good. Perfect fit also. Packaging is nice, resealable sturdy bag. Came fast shipping as well. Two thumbs up 👍 Would give it 10 stars if i could.

As someone who’s tried my fair share of bearings, let me just say—WOW. These bearings have truly set a new standard for performance and quality. From the moment I popped them into my spinner, I knew I was in for something special. Smoothness: The spin is absolutely flawless. It feels like a well-oiled machine (pun intended). Whether I’m casually spinning to de-stress or pushing the limits of my tricks, these bearings hold up effortlessly. No wobble, no noise, just pure, uninterrupted motion. Durability: I’ve been using them for hours on end, and they still perform like they’re fresh out of the box. The build quality is clearly top-notch. I can already tell these are going to last me a long time. Value: At this price point, you’re getting premium performance without breaking the bank. I’ve spent twice as much on bearings that didn’t even come close to what these deliver. If you’re on the fence, let me save you some time: Buy them. You won’t regret it. Whether you’re a casual spinner or a die-hard enthusiast, these bearings will elevate your experience to a whole new level.

This bearing is of great quality and did what it should. I used them for heavy fidget spinners. They have long spin times and spin smoothly. I would definitely buy more if needed.

These work great. I used them on my Tungsten spinner, and it drastically increased spin time. They spin extremely smooth with no real sound or resistance. I’d say they are equivalent to ABEC-9 bearings.

Excellent bearing for my fidget spinner project. It has lesser friction compared to other kinds of bearing.

Just what I needed: quiet bearing for my fidget spinners and spin sticks. As described. Recommend.

These are smaller than the 608 bearings, a mistake I made at first. Until I realized how good these are, and adapters are easy to print for any 608 print piece that can't be altered. Now I use these for the main bearing in a fidget spinner, with cheaper 608 bearings for the external weights. Spins really good, is very quiet (not silent, but I didn't need silence), and is fairly priced for the quality. Definitely enjoying these and have already purchased more, with plans to continue doing so in the future.

Very surprised how smooth and well made these are. The price is amazing. The bearing works well. Smooth and quiet. Definitely a keeper on my list

Questi cuscinetti a sfera sono perfetti per gli spinner. Dopo averne provati molti diversi, finalmente ho trovato quelli giusti. Non è semplice capire qual è l'azienda che li produce perché spesso non viene indicata (in Italia troviamo il nome dell'importatore che, però può rifornirsi da aziende diverse). Questi sono prodotti da Fushi Bearing.
