In recent years, NSK has been developing and manufacturing products in response to the electrification of vehicles, including parts for hybrid cars, electric vehicles, and automobiles powered by fuel cells. NSK is producing compact, lightweight bearings that reduce friction loss and noise, always striving to make automobiles more reliable and fuel efficient.
For instance, both the drive system of the Toyota Prius and the rear axle of the world’s first diesel hybrid car (developed by PSA Peugeot-Citroën) use NSK bearings.
The drive system combines a high-speed electric motor (up to 40,000 rpm) – featuring a reduction gear to boost efficiency and reduce noise – with a dual-speed transmission. This system is hallmarked by its high efficiency and outstanding performance.
