Best ever.

### ⭐⭐⭐⭐⭐ Great little bearings...
*by R***K on April 27, 2024*

I use them as part of internal hinges for laser finger boxes. 2mm stainless shafts fit perfectly and rotate just right, with no slop. Exactly why I purchased them.

### ⭐⭐⭐⭐ MR52ZZ(2mm ID) Great Little bearings. Tight tolerances. Little under 2mm ID. Rusted with moisture.
*by S***R on August 7, 2019*

I bought these for an RC Boat project to use on the output of the drive shaft. These are not stainless and rusted after the first use. They continued to work after breaking the rust free so no problem for me. Will buy stainless next time. Spun up to 25,000 RPM with no noise or vibrations of any kind. Amazing little bearings.
