(100 Pieces) PGN - 5/16 Inch (0.3125) Precision Chrome Steel Bearing Balls G25

Didnt need this many but now Ive got spares ;-) My application is not typical: Im using them as joints in a welded fixture so cant speak to their accuracy but they do what theyre intended. Would have preferred them in crs but thats unobtanium.

Well made

just what i wanted

Just a FYI, these balls rusted in both Reaper and Citadel paints. Ultimately had to throw away two full pots... very disappointed

Used to repair hitch. Worked great.

They rust...Not good for paint mixers!

We used these ball bearings in a Science classroom experiment and they were just the right size. I realize this isnt your normal review but as a Science teacher, the speed of the shipment as well as the item being just as described, was very helpful!

Replaced loose bearings in an old bicycle hub.

I had to replace the bearings on a stationary bicycle. Im a former mechanic so DIY and very happy with the results. The old bearings had shelled apart-and there are questionable quality bearings out there. These passed my rudimentary hardness testing but time will be the test. As always proper installation is a key-snug bearing tight & turn back till no resistance or play is felt-then lock the adjuster. And generous quality lube-done forever I hope.

rusted instantly (after a few hours). Not good for humid environments or uses where they will get wet (anything remotely moist or humid or rainy.) Returning item.
