Need a miniature ball bearing even at the smallest of sizes? We have the NMB precision miniature ball bearing for you. We can supply the 8,500 different types of miniature and small-sized ball bearings designed and manufactured by NMB. Their miniature ball bearings range in size from .1181 inch bore (1 mm) to 1-inch diameter (26 mm). They developed and manufactured an extremely precision and strong miniature ball bearing with an outer diameter of just 1.4978 mm for Swiss watch manufacturers. To put this in perspective, this miniature ball bearing was as tiny as a period on the lettering that appears on a quarter. These miniature ball bearings are ideal for high-precision rotary components in instruments, equipment, and machines of all sizes.  

As a trusted NMB bearings distributor, we offer NMB precision bearings in inch and metric sizes, open or shielded, and flanged or unflanged. We also carry stainless steel or high carbon chromium (or chrome) steel NMB ball bearings, each of which offers unique physical and mechanical properties.
