Ball bearings are machinery components, which comprise an outer ring, inner ring, balls, retainers, shields and snap rings. Miniature and small-sized ball bearing mean ball bearing, up to 30mm in external diameter. Essential to high-precision rotary components, ball bearings determine rotational accuracy. Features A Broad Range of State of The Art Products MinebeaMitsumi manufactures more than 8,500 different types of miniature and small-sized ball bearings, most of which have external diameters of 22mm or less. In addition to such specialized products as integrated-shaft ball bearings, MinebeaMitsumi manufactures fluid dynamic bearings, for which demand is expected to soar in the future. We are thus positioned to respond to demand for a broad range of state-of-the-art small bearings for high-precision motors and other applications. Integrated-shaft ball bearings Integrated-shaft ball bearings An integrated-shaft ball bearing has two raceways on the shaft, allowing the integration on the inner ring and shaft of two ball bearings. The facilitates more precise rotation than is possible with two independent ball bearings, making integrated-shaft ball bearings particularly suited to applications such ad cylinder units for video cameras. Ultra-precision Machining Technology The precision of a ball bearing is determined by several factors, including the raceway roundness of the inner and outer rings, the sphericity of the balls and the quality of the balls and the quality of the raw materials used in each of the bearing's parts.Improving precision demands uncompromising strictness on all counts.
