(25 Pieces) PGN - 1/2 Inch (0.5) Precision Chrome Steel Bearing Balls G25

Theyre pretty cool using them for a marble track. Standard marble is not a half inch by the way so I just scaled my marble track down but they are a great product perfect for my application.

happy with product

We use them in our after school program to test the viability of our engineering projects.

They make great grapes

Needed bearings for one of my projects, these did the job perfectly. No surface imperfections, and they worked without an issue.

The product was fine and the shipping was really fast.

I received what was advertised. I used it for a baseball pinball game I made for my grandkids.

Decent price for a healthy handful of ammo (~_^ )

The bearings arrived quickly for a hobby project involving magnets and ball bearing. The bearings worked fine. DaVinci would have been proud.

Just what I needed, everything was in great shape. No rust or deformities.
