Smooth Operation

Great for 3D printer fans. They are quiet and the stainless steel ensures they won't degrade quickly.

Quality Steel

I was worried about rust since I use these in a humid environment. No rust after three months of use. Very satisfied.

Perfect for RC Cars

Using the 5mm bore bearings for my remote control car motor. They spin smoothly and fit perfectly without any wiggle room.

Good Value

Overall great bearings for the price. One bearing in the pack was slightly noisy, but the rest were perfect.
