NSK（China）Investment Co.,Ltd
NSK (China) Investment Co., Ltd. is the headquarter of NSK Ltd. (NSK in short) in China, NSK has set up more than 30 production plants, R&D centers, sales companies and subsidiaries throughout China. NSK (China) Research and Development Co., Ltd. is NSK's largest R&D center outside of Japan, with the first-class level of design and development capabilities. NSK provides diversified product solutions for automotive evolution and has won the favor of many well-known automotive related enterprises. In response to the demand for high-voltage and high-efficiency of E-axle, NSK provides bearing solutions for high-efficiency and high-reliability electric drive systems. In addition, NSK has developed a 2-speed shifting solution that realizes smooth shifting without torque interruptions through the combination of a centrifugal multimode clutch (CePaC) and an electronically controlled multi-friction plate clutch (eCuPa).
