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

I put these in the bottom bracket of an old bike with one piece crank that had old rusted ball bearings. Working fine.

They appear to be very precise and high quality. The price and shipping time were both very nice as well.

the ball bearings were delivered quickly and they were the right thing i needed.
