In the bearing application of NTN for high precision industry, how to minimize the coefficient of friction and improve energy efficiency? The NTN bearing technology has achieved the nanometer class precision with the size of nanometer unit. The precision, only the extravagant hope previously, has been used in various areas with demanding precision, such as orbit satellite, aviation, and high precision instrument etc. The NTN precision processing technology and unique proprietary technology developed gradually based on the long-term bearing development and now they have been widely used in the precision machinery for all the production areas. It is the new symbol for NTN development to continuously create new value.
