50x ZrO2 Zirconia Ceramic Bearing Balls – 5/16 Inch (7.938mm) – High-Quality, Unbranded

Here’s a pack of 50 precision ceramic bearing balls made from ZrO2 zirconia oxide.

Each one is 5/16-inch or 7.938mm in diameter—super consistent and ready for whatever project you’ve got going.

They’re brand new and unused, though they come in simple non-retail packaging.

No brand name, no frills, just solid little balls that get the job done.

MPN and UPC don’t apply here.
