ANN ARBOR, Mich.: NSK’s green automotive technology was the centre of attention at the 41st Tokyo Motor Show held Oct. 24 to Nov. 4.


The Japanese bearing company’s products and technologies are helping to reduce CO2 emissions and improve vehicle safety. US-based automotive companies are currently using five KSK technologies:

• Ultra high-speed ball bearings for the motor and generator in next-generation hybrid cars achieve 30,000 rpm or more (1.5 times that of conventional bearings), increasing fuel efficiency and power.

• Low-friction torque ball bearings for hybrid cars designed for transmissions reduce energy loss through friction by up to 65 per cent. This product has enhanced the fuel economy of the Toyota’s low-fuel Prius.

• Brush motor and mechatronics (ECU, torque sensor board, gearbox and torque sensor coil) are integrated into one unit to achieve the shortest column length in the world for small vehicles in the world, which contributes to smoother manoeuvrability and improved fuel economy.

• Highly reliable hub unit bearing for BRIC countries (Brazil, Russia, India, China) where the demand for automobiles is on the rise.

• The world’s smallest roller (1.5 mm in diameter) with maximum rotation 1.5 times that of conventional products, for increasingly diverse and faster transmissions such as belt CVTs, ATs and hybrid automobile transmissions.
NSK’s CSR and Socially Responsible Investment efforts have earned the company recognition on the Dow Jones Sustainability World Index, the FTSE4Good Global Benchmark Index, the Ethibel Sustainability Index, the Morningstar Japan SRI Index and the Global 100 Most Sustainable Corporations list from the World Economic Forum.
