Miniature Ball Bearings

FITRUN miniature ball bearings refer to deep groove ball bearings with a bore diameter of 1 to 9 mm, which are available in both metric and inch sizes. They have significant advantages such as high speed, low noise and long life. Miniature ball bearings are also called micro ball bearings, instrument ball bearings and mini ball bearings.
