NSK
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 E-axle, the measured voltage/current of each bearing varies with the rotational speed/torque under different combinations of countermeasures, and the optimal combination is explored to realize the win-win situation in terms of effect and low cost by NSK. And for product, NSK conductive paper-based products demonstrated strong potential for preventing bearing electrical erosion by providing controlled current paths, as well as for addressing EMC issues through improved electrical grounding.

Product 1
Development technology/material/manufacturing process nameBearings with resin molding for electrical corrosion solution
Innovation Highlights By applying resin molding on the outer diameter/inner diameter and end face of the bearing that can isolate the transmission of current, it can effectively improve the shaft voltage resistance performance. Compared with traditional ceramic ball bearings, it has good cost-balance.
