## Description

SpinnerHub sells a large variety of fidget spinners and we are very serious about our bearings! These Hybrid Ceramic 688s with Silicon Nitride balls are the absolute top of the line in fidget spinner bearings. Most new spinners come with 608 bearings because their smaller size allows for longer spin times. These will be an upgrade for any spinner with a stainless steel 688 bearing and they are perfect to have around in case your fidget spinner bearing gets dirty or breaks. Prime shipping means it will arrive super fast. Please don't hesitate to contact us with any questions!

## Customer Reviews

### ⭐⭐⭐⭐⭐ 







  
  
    Excellent bearings - upped my fidget spinner times to over 5 minutes!
  

*by T***U on Reviewed in the United States on July 16, 2017*

I'm a bit of a fidget spinner obsessive and recently got into upping the spin time performance of some of my higher end spinners with better bearings. Highly recommended for all you fidget spinner aficionados out there.These bearings were great. Smooth. Well made. I swapped this 688 replacement bearing into my FEGVE Titanium Tri and it's spinning for five+ minutes. It definitely increased my spin times noticeably. I also have a ZenDial Tivium and given the performance on this bearing, I'm planning to buy this vendor's 608 bearings for that.

### ⭐⭐⭐⭐ 







  
  
    Not for 3D printers...
  

*by A***I on Reviewed in the United States on July 5, 2017*

Very nice bearings but don't use them for 3D printer mods. They tend to vibrate a lot when they shake around and are just spinning slowly. Very noisy. I will print a fidget spinner and use them there!

### ⭐⭐ 







  
  
    Too small
  

*by M***K on Reviewed in the United States on July 24, 2017*

I had looked and looked to make sure these were the right size for my son's spinners the spinners they showed were identical, however these were too small at the OD. Outside diameter.
