Railways

NSK developed to provide high performance, high reliability and long-term maintenance of the various railway vehicle bearing (axles, drive mechanism, with the main motor), support "safe and stable destination" railway mission.
Having Shinkansen 0 series from the original to the latest N700 series performance it has been widely used as a vehicle bearing grease seal to provide the type and oil bath lubrication type. Further, the vehicle bearing and safety closely, NSK developed may have a bearing on the state of the monitored object with a sensor bearing. In addition, the drive means in harsh environments with vibration and bearing ribs bite-resistant adhesive based on specifications, nitriding with high strength cage NSK independently developed high reliability bearings.
Furthermore, the development of the application in the main motor bearings can meet long maintenance cycle, superior performance and utilization grease supply failure security holder Thought. For application of the life of the bearing grease having more than 2 times the original size. The use of ceramic insulating resin insulated bearings and bearing a settlement against electric food maintenance issues. However, NSK bearings for truck vehicles sealed tapered roller bearings, AAR certification is being made in the United States
