100 3/8" Inch Chrome Steel Bearing Balls G25

I'm very happy with the quality of these bearings. They have a nice finished and a light oil I presume to keep them from tarnishing. I bought them for my son who 3d printed a marble tower.

I use these with a marble obstacle course made by PlayMonster. It's the Marbleocity set (mine is the Stake Park). They come with bearings, but not enough to really saturate it. This is the correct size to work with that set, so I recommend it for anyone buying a Marbleocity set (or at least, anyone buying one of the larger sets). It's indistinguishable from the ones that come with it.

All pros no cons great value too

I'm not sure just how to rate these since I ordered 3/8" steel bearings and this it the exact product. All are chromed and shiny, exactly like you'd expect. I'm using them as marbles in a 3D printed marble machine. They work fine and are exactly the size needed. Good product, good price.

Works perfect for what I needed!!!

These worked wonderfully in my 3D-printed Marble Machine #3. Of course, this application requires basically zero precision (even an oblong spheroid would work) so don't take this review seriously if you actually plan to use this in something important.

I used these bearings for a motion application and so far I am happy with the surface and quality

I got this for a clutch for a 1985 threewheler. Shop wanted 15$ for one I got 100 for under 4$

I purchased these ball bearings for use with the "3D Printed Marble Machine #3" (which you can find on Thingiverse). The marble machine is sized for 3/8" marbles, and these worked perfectly.

I bought these to replace some bearings in a ham radio antenna rotor.. works perfect,and they are of high quality.. I bought another pack of 100.. excellent /

Works as specified

Excellent product. Exactly as described. Shiny no scratches.

This product was just as advertised and I am using these balls in a six inch bearing for an antenna rotator.
