Railway bearings are safety-critical components that have a direct influence on the safe operation of railways. They must be highly reliable. In addition to consistent reliability, they are also required to be light and compact to conserve energy and reduce the impact of railways on the environment. Bearings used in rapid trains, which carry passengers to many train stations at rapid speed, need to ensure good ride comfort and need to have high durability and good maintenance. NSK has been constantly further improving the reliability and functionality of railway bearings for many years. This new product, which is Japan's first passenger train car sensor bearing, makes it possible to constantly monitor the rotation speed of the axle bearing for improved safety and reliability.
This product is expected to be used in a wide variety of applications: not only does it improve safety, it also reduces maintenance workload. Additionally, this sensor houses multiple sensing functions (temperature, vibration, rotation speed), making it expandable as a high functionality multi-sensor.
