Minebea was founded in 1951 as Japan’s first manufacturer to specialize in miniature ball bearings. At present, the Minebea Group encompasses 42 subsidiaries and affiliates, which operate 36 manufacturing plants and 40 sales offices in 18 countries and employ over 50,000 people.

Minebea’s main product line is ball bearings. Minebea is the world’s leading manufacturer of miniature and small sized ball bearings, up to 22mm in external diameter, and has a global market share in excess of 60%. Minebea’s bearing line also includes a broad selection of rod-end, spherical and other bearings for the aerospace market.

Miniature ball bearings are useful in a wide variety of applications. Bearings in general are devices that allow parts to move relative to one another in a constrained fashion. This motion may be linear or in rotation. The two most common types of bearings are plain bearings and rolling bearings. The most well-known of the rolling variety of bearings is the ball. A ball bearing can be highly effective at reducing friction between two parts that need to move freely. There is some elasticity to the ball allowing it to support and move a range of bearing loads. Naturally, the balls in such bearings come in a variety of different sizes, from fairly large to miniature. Small Bearings can be extremely useful in applications where space is limited, such as automotive, electrical  and medical devices.

NMB’s wide variety of miniature bearings means that you are certain to find just the bearings you are looking for. Use the bearings search fields to find the bearings you need. Search by bearings size according to inch or metric measurement and by inside diameter size and outside diameter size.
