Miniature & small sized ball bearings
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.

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
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. Building on expertise amassed over 50 years, MinebeaMitsumi has developed high-precision machining equipment, sophisticated maintenance technologies and efficient plant-line layouts, enabling it to produce all parts for its bearings in-house and to aim constantly for higher levels of precision.
Consistently Superior Quality Worldwide
MinebeaMitsumi currently has 10 bearing plants worldwide, all of which conduct vertically integrated production, which encompasses all processes, from machining to final assembly and testing. These plants also utilize mass-production technologies and production lines developed at MinebeaMitsumi's parent plants in Japan. As a consequence, MinebeaMitsumi is able to guarantee products of consistenly superior quality from all of its bearing plants.
Global R&D Activity
R&D centers located within MinebeaMitsumi's parent plant in Japan, Thailand and Singapore conduct chemical analysis, cleanliness evaluation of products. And we have facility for evaluation and testing of products for use in automobiles.
