Improved fuel economy and reliability automotive Seiko Co., Ltd. (NSK, Headquarters: Tokyo, Japan; President and CEO: Otsuka Norio) today announced that it has developed a highly efficient tapered roller bearings used in automotiveThe differential gear and gearbox friction loss has been reduced by approximately 30%. NSK will launch this product in the December 2016 target annual sales of 2 billion yen. The development background tapered roller bearings are widely used in automotive, especially in the position requires a high level of support stiffness and must bear the load of high-strength. In order to improve the fuel economy, the challenge is to find a way, these bearings to reduce friction loss. Tapered roller bearings, NSK to respond to this challenge, the use of its proprietary design technologies to improve the efficiency advantage of the latest analytical techniques, tapered roller bearings have a higher efficiency. The development of fourth-generation product characteristics. Special uplift, while maintaining the same or greater life, can withstand heavier loads, through the use of the guide surface of the cylindrical shape of the inner ring and the outer ring, and achieve a smaller friction can be reduced edge loading is called as particularly crowing and additional rigidity compared to traditional products. The internal design of NSK optimize the internal design optimization by causing the change of the number and length of the roller and in doing so, contact angle, etc., friction loss is reduced by 30%, the durability is improved by about 1.5 times, thereby making it possible to small technology further. Applications such as the new NSK tapered roller child bearing can support a wide range of applications requires a high level of rigidity and withstand heavy loads, such as differential gear, manual and automatic transmission cars use product advantages compared to traditional bearings bearing friction loss is reduced by 30%, thus helping to improve fuel economy and extra lives. In addition, can also be used the bearing routine applications in the field of ball bearings.
