Deliver high quality and sub-micron precision nearly every rotation need
Miniature ball bearings have become essential components in the rotating elements of various equipments and machines. In response to the trend toward equipment and machinery that gets smaller, more compact, thinner and quieter, we manufacture hundreds of kinds of miniature ball bearings, including specialized types, from extremely small bearings with a 1.0 mm bore diameter and a 3.0 mm outer diameter to bearings that are about 20 mm in outer diameter.
Single-row deep groove ball bearings
Consist of inner ring, outer ring, balls, retainer and cage. This type is the most generally used radial ball bearings for many applications.
We, NSK Micro Precision Co., Ltd. (ISC), have succeeded in manufacturing the world's smallest-diameter deep groove ball bearing with an outer diameter of 2 mm and a bore diameter of 0.6 mm.
Deep groove ball bearings with extended inner rings are inch series bearings with their inner rings extended equally on both sides by 1/64 inch
