## Description

desertcart.com: JIUWU 10 pcs 3x6x2.5mm Ball Bearings MR63ZZ L-630ZZ 673ZZ Bearings Miniature Deep Groove Ball Steel Bearing : Industrial & Scientific

Review: Bearings are just right for small project - I have not had any problems with the miniature bearings. I needed them for a 3D printed train axle. The bearings fit the brass rod and inserted into the train with no problems. The bearings were exactly as described.
Review: These are the correct dimensions - 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

### ⭐⭐⭐⭐⭐ These are the correct dimensions

### ⭐⭐⭐⭐ Low quality bearings, but great in a pinch and half-decent tolerance
*by A***Y on June 17, 2021*

Low quality bearing but great for the low cost and great in a quick pinch, especially with McMaster-Carr being out of almost all steel bearings.
