### ⭐⭐⭐⭐⭐ Bearings are just right for small project
*by S***Y on December 4, 2024*

### ⭐⭐⭐⭐⭐ Works
*by M***E on January 17, 2026*

As described

### ⭐⭐⭐⭐⭐ These are the correct dimensions
*by M***T on March 25, 2022*

I almost didn’t buy these because some reviews said the dimensions are way off, but I went for it and am glad I did: they do have an ID of 3mm, an OD of 6mm, and a thickness of 2.5mm. I also bought some 3x7x3 bearings just in case, and am glad that I don’t need to use those because they wobble quite a bit on a 3mm rod. Meanwhile these ones are actually impressively solid by comparison, with very little wobble. All in all a great mini bearing
