We offer over hundreds of miniature ball bearings, ranging from ultra-small types with an inner diameter of 1.0mm and an outer diameter of 3.0mm to sizes around an outer diameter of 20mm!
Miniature ball bearings are now essential components in the rotating parts of various equipment. As the downsizing of equipment progresses, there is an increasing demand for smaller, thinner, and quieter designs. NSK Micro Precision Co., Ltd. manufactures a variety of ball bearings tailored to meet these needs. ■ Size Types From ultra-small types with an inner diameter of 1.0mm and an outer diameter of 3.0mm to larger sizes around 20mm in outer diameter, including special types, there are hundreds of varieties. ■ Catalog Contents The "Miniature Ball Bearing Comprehensive Catalog" includes the most commonly used radial ball bearings composed of an inner ring, outer ring, balls, cage, and seals, such as "Single Row Deep Groove Ball Bearings," deep groove ball bearings with a flange on one side of the outer ring, "Flanged Deep Groove Ball Bearings," inch series deep groove ball bearings with a wider inner ring than the outer ring, "Wide Inner Ring Deep Groove Ball Bearings," and deep groove ball bearings with a smaller outer diameter-to-inner diameter ratio than standard, "Thin-Walled Deep Groove Ball Bearings," among many others. ★ For more details, please download the catalog or contact us.
