They work great Review: Best purchase ever! Put them in all my spinners - 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. ## Features - High Speed Ball Bearings - R188 Bearings Are Open Type For Easy Lubricating - Bearing With Nylon Cage：Low Noise, Light Weight, It Can Effectively Extend The Service Life Of Bearings - These Bearings Is Good For DIY Your Own Fidget Spinner Toys And Its 10 Steel Balls Allow For A Smoother And More Stable Spinning Experience. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B095GTJC1R | | Bearing Number | R188 | | Bearing Type | Ball Bearing | | Bearing number | R188 | | Brand | FUSHIBEARING | | Brand Name | FUSHIBEARING | | Compatible Lubricant | Grease | | Customer Reviews | 4.7 out of 5 stars 119 Reviews | | Item Dimensions | 13 millimeters | | Item Thickness | 4.8 Millimeters | | Item dimensions L x W x H | 13 millimeters | | Item thickness | 4.8 Millimeters | | Manufacturer | FUSHIBEARING | | Material | Alloy Steel | | Material Type | Alloy Steel | | Model | R188 | | Number of Items | 10 | | Outside Diameter | 12.7 Millimeters | | Part Number | R188 | | Specification Met | ABEC 1 | | Specification met | ABEC 1 | ## Product Details - **Bearing number:** R188 - **Brand:** FUSHIBEARING - **Item dimensions L x W x H:** 13 millimeters - **Item thickness:** 4.8 Millimeters - **Material:** Alloy Steel ## Images ![R188 Open Deep Groove Ball Bearing, 1/4"mmx1/2"mmx3/16"mm Fidget Spinner Bearing with Nylon Caged (10 PCS) - Image 1](https://m.media-amazon.com/images/I/81aQo-N57YL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Favorite bearings *by N***S on 17 May 2026* Getting for a second time.
