Develop and provide high-performance, high reliability, and long-term maintenance of various railway vehicle bearings (including main motor shafts and transmission mechanisms) to support safety and stability goals; The mission of railways. The performance of the latest N700 series has been widely used in the 0 series Shinkansen for automotive bearing grease sealing and oil bath lubrication. In addition, vehicle bearings are closely related to safety, and a bearing has been developed that can monitor the status of the monitored object and sensor bearings. In addition, the vibration and rib biting adhesive of the bearing in harsh environments are driven by a specification based drive device, which has a high-strength cage nitriding and independently developed high reliability bearings.

In addition, the application development of main motor bearings can meet the long-term maintenance cycle, superior performance, and the idea of utilizing lubricating grease supply failure for safety holders. Suitable for bearing grease with a service life greater than twice the original size. Using ceramic insulation resin to insulate bearings and bearings to solve electrical and food maintenance problems.
