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

Worked out great for my project

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.

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.

I only needed this as a replacement in a table top pin ball game. It works.

Good product as described

ok quality

I used these for detent balls in British transmissions. Hard to find but Amazon to the rescue.

I only needed one, but I got 100 for less than it would have cost at the motorcycle shop.

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.

They arrived very fast and where just as advertised!!!
