MinebeaMitsumi primarily manufactures single-row, deep groove rolling ball bearings. NMB branded radial deep groove ball bearings are available open or with a shield or seal to prevent grease from leaking out and ingress of foreign matter. Flange type and snap ring type bearings offer improved housing fits. We also produces ultra thin type radial ball bearings, thrust ball bearings, special bearings, and customized variations.
