Ball bearings are machined components that include an outer ring, inner ring, balls, retainers, shields and snap rings. NMB's miniature ball bearings are available in inch and metric sizes, open or shielded and flanged or unflanged. For extreme noise sensitive applications, superior hardness and corrosion resistance our ball bearings are manufactured with DD400™ stainless steel material. Chrome steel is available for applications in uses and environments where corrosion resistance is not a critical factor.
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 aerospace products 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.
