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 and high-efficiency of E-axle, NSK provides bearing solutions for high-efficiency and high-reliability electric drive systems. NSK newly developed narrow combination type cage combining with bearing long life technology, can reduce the bearing width and realize compactness and light weight of ball bearing.In addition, basing on raceway crowning and oil-poor lubrication technology, solved the subject of optimizing the number of rollers, reduced the torque of tapered bearing.

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.
