NSK Ltd. (NSK; Headquarters: Tokyo, Japan; President and CEO: Norio Otsuka) today announced that it has developed a quiet, low-friction ball bearing that achieves low friction at a wide range of temperatures, and quiet operations in cold temperatures. Its main application will be for electric vehicle (EV) drive motors.
NSK improved the grease fluidity and optimized the bearing to reduce grease agitation resistance and bearing vibration during operation in cold temperatures. As a result, this new ball bearing for drive motors can achieve low friction and quiet operations, thereby helping to provide improved driving range and quietness for EVs.
NSK is targeting 500 million yen in global annual sales in 2020 for this new product.
