Research and Development

 NTN
began as a bearing manufacturer. Since our founding in 1918,
we have conducted research into new materials including functional
resins and ceramics. From there we conducted research into the
measurement technology that is indispensable to the precision
processing that produces bearings, in addition to improving
the work of grinding and lubricating materials surfaces.We have also utilized our basic research results and expertise gained through the years to evolve from a manufacturer of bearings to advanced precision processing equipment. In addition, we are conducting research and developing production facilities to create a wide range of precision processing equipment at home and abroad. |

 NTN's
laboratories are active in R&D in every sector. These laboratories
do more than merely exchange information and form ties with
other divisions. They actively go outside the company to meet
and talk with R&D divisions of customers and conduct joint
research with universities.For example, we have solved problems by using needle bearings in extremely narrow spaces where conventional ball bearings cannot be used. And we have affirmed our position as one of the leading manufacturers of needle bearings. We are also involved with new product development and trials conducted by customers, and resolutely meet new challenges in a wide range of sectors, including automobiles, computers, medical equipment, aerospace, and industrial robots. |

 NTN
is a precision device manufacturer that continually develops
new products in new sectors.We have developed a bearing with a hydrodynamic groove in the surface of the bearing's inner diameter. The hydrodynamic bearing, with metallic powder compressed and sintered, is already being mass-produced for the polygon scanner motor on laser beam printers. The expertise acquired in developing this product is also finding application in the spindle motor for hard disc drives - our next development target. It was commercialized as the "Hydrodynamic BEARPHITE Unit" (patent pending). This product is compact and features high rotation accuracy. It is perfectly suited for use with information equipment because it is quieter than ball bearings. As a result, companies from many different sectors are placing orders. |
