Review on 🔩 Uxcell 2mm x 5mm x 2.5mm Shielded Miniature Bearing - Power Transmission Products by Joseph Meola

out of 10 only six (6) were good. One was fully caught and three rolled very hard. The worst thing is that the hole diameter is just under 2mm. I have 2mm thick stainless steel shafts which I measured with vernier calipers and found 1.9mm. The bearing bore is a bit narrow and I can't get the shafts into the bearing securely without a lot of force. The diameter of the hole is about 1.8mm to 1.85mm based on my estimates. That being said, it's pretty hard to find 2mm bearings for less than $20 each so you get what you pay for.
