In order to secure operating revenue and develop the business, NSK protects new products developed with its original technology. NSK has established a long tradition of active patent application filing, concentrating not only on original technologies, but also on improving the quality of existing patented technologies.
NSK has developed the Dual Pitman Arm Steer by Wire System (DPASS) and exhibited it at the 40th Tokyo Motor Show 2007. Utilising information from multi- sensor hub unit bearings, the DPASS controls steering of the left and right front wheels independently of each other. In addition to expanding cabin space, enhancing fuel economy and safety, it makes possible advanced active steering control, which may lead to automated driving in the future.
Biodegradable plastic is increasingly used in everyday consumer goods. NSK has developed a high- strength, biodegradable plastic with superior heat resistance. It presented sample bearings complete with cages and seals made of this plastic in January 2008. This high-strength biodegradable plastic is adaptable to a wide array of applications.
