Research & Development
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.
- Domestic (Japan) public disclosures totaling 1.467 in fiscal 2007: NSK maintains the lead in corporate patent applications in the mechanical parts field.
- NSK concentrates not only on filing patents for original technologies, but also on improving the quality of existing patented technologies through close coordination between technology departments and the intellectual property department.
- NSK holds many registered patents, including 1.427 in Japan and 2.008 outside Japan..
- NSK promotes company-wide measures in collaboration with relevant authorities to combat counterfeit products in various countries.
Automotive Products
- The world’s first lightweight and cold-formed hub unit bearings for passenger vehicles.

Development of Dual Pitman Arm Steer by Wire System (DPASS) enabling independent steering control of the left and right front wheels
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.
Industry Machinery Bearings
- Quiet-running, long-life ball bearings for fan motors operating in high- temperature environments.
- Ultrahigh accuracy, ceramic, angular contact ball bearings for machine tool main spindles.
- High speed, long life cylindrical roller bearings employed an automated grease replenishing system.
- A new series of long-life split cylindrical roller bearing units for segmented drive rolls that contribute to a cleaner working environment used in steel mill applications.
- A new series of highly corrosion-resistant self-aligning ball bearings.
- The world’s thinnest microactuator pivot ball bearing assembly for ultra-thin 2.5mm HDDs.

Development of High- Strength Biodegradable Plastic with Superior Heat Resistance
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.
