In a fluid dynamic bearing (FDB), a thin layer of oil or other lubricant is injected between the shaft and sleeve. The structure of the bearing features a rotating shaft, which generates a hydrodynamic force, causing the shaft to rotate. The non-contact construction of this bearing makes it particularly suited for improving rotational accuracy and enhancing quietness and robustness.

Used in bath scales, various other types of scales, game consoles, home appliances, load sensors, etc., these sensors are sensors for mass production that use strain gages.

Minebea's lighting devices are the parts used for fine color liquid-crystal displays (LCDs) for cellular telephones, smart phones, tablet PCs and personal digital assistants (PDAs). As LCDs cannot generate light on their own, backlight systems which consists of a reflector, a guide plate, and prism sheets that illuminate from behind the displays are essential. The system comprise white light-emitting diode (LED) chips and transparent plastic panel made from micron-order prisms for controlling light.

Strain gages consist of a very fine and thin metallic foil etched in a grid pattern, which is bonded to a device and used to measure the strain, or amount of deformation of the device when load or pressure is applied. The resulting electrical output is proportional to the strain.
Because these strain gages are so small that they are negligible in mass, they excel in sensitivity, stability and fatigue with no inertial effect. They are also an easy-to-handle device, whose operating temperature range is wide. The strain gages can be used to measure the strain of all kinds of materials, regardless of metal or plastic.
