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.

Autorail Grande Capacité (AGC) FAG wheelsets and drive bearings in AGC. In 2007, Bombardier Transportation manufactured 500 AGC new area express trains for SNCF. According to the requirements of the French National Railways, AGC meets the needs of the French region due to its wide range of models.

That is to say, it can only be provided for AGC 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. AGC provides drivers with more flexibility, shorter stops, and more space and comfort for passengers.

FAG provides ready-to-install tapered roller bearings and axle boxes for all AGC models.

The design of modern rail vehicles requires a high degree of passenger comfort, low noise and economy. Rolling bearings developed by Schaeffler Group's industrial division 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.

The increasing demand for control and monitoring systems in the railway transportation field requires vehicles to conduct comprehensive data collection during operation. More and more wheelset bearing information is used for the needs of various vehicle systems. Including speed signal, direction monitoring, and monitoring of bearing temperature as an additional function of thermal operation monitoring.

The Schaeffler Group Industrial Division has developed wheelset bearings with integrated sensors (ready-to-install modules with integrated sensors), which have been optimized to meet the requirements of railway transportation.

The sensor reliably transmits relevant speed information to the wheel slip and braking system, speed indicator, door closing mechanism and rolling recognition system. Continuous temperature for early thermal operation recognition
