I had problems sourcing this size ball bearing locally. They had a great variety and the order was processed extremely quick. Delivered within a week.

Fixed my trackball
June 21, 2011
I have a IOGear keyboard with a built-in trackball that rides on three little ball bearings. The bearing balls don't turn so the trackball wears flat spots on the bearing balls. I have replaced the keyboard once and was ready to send it in for warranty repair when I decided to try to find bearing balls to fit. I don't have a micrometer but I could tell the size pretty close. I should have known the keyboard was made in Asia and the bering balls would be metric but I ordered the 3 32 balls as well as the 2.5mm. The 2.5mm fit perfectly and now I can repair my keyboard 82 more times.
