High-precision dynamic pressure fluid bearings

Polygon mirror scanner motors manufactured by MinebeaMitsumi contain high-precision dynamic pressure fluid bearings to provide greatly improved precision and reliability. In particular, we have designed and developed fluid bearings for our own polygon mirror scanner motors, and manufacture these fluid bearings in-house at our factories in Japan and in Zhuhai, China. This comprehensive manufacturing structure allows us to respond to the various different needs of our different customers.

All major components manufactured in-house

Gear shafts, rotor frames, neodymium magnets, cores, housings, and all other major components are manufactured in-house at one of our company's own factories for greater competitiveness in terms of quality, on-time delivery, and manufacturing costs.
