In the field of railway transportation, EMUs are vehicles used to provide power. An EMU can be a traction unit of a locomotive or EMU, that is, it can only be provided for internal combustion or electric drive, or it can be a combination of internal electricity. It is also possible to change the transportation capacity by linking two to four carriages.

Due to the modular design (that is, the same components are used), maintenance and service are very simple, although there are more models. It provides drivers with more flexibility, shorter stops, and more space and comfort for passengers.

Provide ready-to-install tapered roller bearings and axle boxes for all models. The design of modern rail vehicles requires a high degree of passenger comfort, low noise and economy. Rolling bearings developed by the industrial sector used in railway transmission systems make this possible.

Various ball and roller bearings are used to guide the drive shaft. As described below, various types of bearings such as deep groove ball bearings, spherical roller bearings and angular contact ball bearings can be used. Railway transportation is increasingly The increasing demand for control and monitoring systems requires vehicles to conduct comprehensive data collection during operation.

More and more wheelset bearing information is used for the needs of various vehicle systems. These include speed signals, direction monitoring, and bearing temperature monitoring as an additional function of thermal operation monitoring. The industrial sector has developed wheelset bearings with integrated sensors, which have been optimized to meet the requirements of railway transportation.
