5.0 out of 5 stars Great little bearings...

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.

4.0 out of 5 stars MR52ZZ(2mm ID) Great Little bearings. Tight tolerances. Little under 2mm ID. Rusted with moisture.
Reviewed in the United States 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.

5.0 out of 5 stars Works to improve Lego train car bogies
Reviewed in the United States on February 25, 2019
I used these to create more realistic looking freight and passenger train cars' bogies (trucks). They roll better than the standard Lego wheel holders. The fit in a technic pin hole with a little bit of extra force.

5.0 out of 5 stars Great little bearings that are self sealed and work perfect for hobby projects
Reviewed in the United States on June 17, 2021
These little bearing are well-engineered, self-sealed, and lubricated. I've used them in many projects and have ordered them several times over. Highly recommend them. They are also very strong.

1.0 out of 5 stars Useless Junk
Reviewed in the United States on December 30, 2021
The inner diameter is smaller than 2mm which means they are useless for the rods I need them to go on. Secondly they do not turn very well which is a big issue for a bearing to have. Save your money and find different ones to buy
