How it all began - with NMB ball bearings

MinebeaMitsumi began in 1951 with the production of miniature ball bearings, operating at that time under the name Nippon Miniature Bearing Co., Ltd. (NMB), and today it has become that market segment’s world leader. The original core business is still the core competency today. In the area of miniature ball bearings with an exterior diameter of less than 22 millimeters, MinebeaMitsumi’s worldwide market share is 60 percent. Millions of miniature ball bearings are supplied each month to customers throughout the entire world.

Precision ball bearings

The NMB bearings are produced with a passion for precision and are, of course, subject to the highest quality standards. Depending on the requirements, their external diameter ranges from 1.5 to 30 millimeters. The ball bearings can be ordered in a great many variations in stainless steel or chrome, flanged, open, or shielded—in other words, exactly as required for your application! All NMB ball bearing components are efficiently and therefore cost-effectively manufactured in our own facility.
