NMB is the world’s largest manufacturer of miniature and instrument ball bearings, producing 150 million bearings per month. Our miniature bearings range in sizes from .1181 to 1.000 inch O.D. (3mm to 26mm), and are available in inch and metric sizes. Standard inch and metric series radial bearings carry moderate radial and thrust loads at low operating torque and provide high performance within small envelope designs. Stainless steel or chrome steel bearings are available with crown or ribbon type metallic cages, as well as plastic crown type cages. Open or shielded bearings may be flanged or unflanged. Various types of seals may be specified depending upon the anticipated environment to which the bearings will be exposed.
