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

Have run these bearings for 336 hours straight w/o a failure. Excellent service and product. You wont be disappointed.

Simply delivered my simple order, quickly.

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.

Size is perfect for smaller monkey fists...will order again when needed.

Exactly what I ordered. But I I am a dumb dum and ordered the wrong size. Lol

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

Needed these for a project.

Use these to hold irregular parts in my milling vise, they are round and hard, thats all I can ask for.

Perfect for science experiments!

Ive not seen one defect.
