Improved efficiency for hybrid vehicles
In recent years, demand for hybrid vehicles has been rising rapidly, thanks to the low fuel consumption and low emissions realised through a more efficient integration of the engine and electric motor. In order to further improve fuel efficiency, there is a growing need to reduce torque loss in the bearings used in the transmissions.
NSK has met this need with its new low-torque bearings, which dramatically reduce frictional loss. To date, most observers considered it too difficult to achieve further reductions in the torque loss of ball bearings. Despite this, NSK has found a way to cut torque by 50-65% compared to existing product. Going forward, NSK expects growing sales to automobile manufacturers of hybrid vehicles in and outside Japan.
