Wheelset Bearings with Integrated Generators FAG wheelset bearings with integrated generators are the ideal solution if railway wagons need to supply power to power monitoring equipment. The magnets in the axle end glands rotate together with the axle, while the coils integrated in the axlebox end caps act as stators to remain stationary. The electrical energy generated in this way is stored in the battery and can be used even when the train is stopped. Therefore, telematics systems with other functions such as wheelset bearing diagnostics and dangerous goods monitoring can transmit information quickly due to an adequate, continuous power supply. There are currently two systems: a 5-watt low-power version and a 100-watt high-power version. If the user needs a special solution, it can be achieved by changing the voltage, such as 6 V~24 V. The amount of work required to install the generator is minimal: just replace the original axlebox end caps and axle end glands of the UIC or Y25 axleboxes with the generator-mounted components. Wheelset bearing with sensor system Engineers at the Schaeffler Group Industrial Division have developed and optimized a wheelset bearing unit with an integrated sensor system (including bearing, sensor and axle box). Sensors reliably transmit information such as speed to anti-skid devices, braking systems, tachometers and automatic door closing systems. The measured continuous temperature value is used to monitor the bearing condition. Therefore, any problems can be detected at an early stage and adjusted in a predetermined pattern. The sensor system can also continuously generate rotational direction information for the newly developed Rail Traffic Management System (ERTMS/ETCS). Ordering example: F-809 915.TAROL 130/210FAG spherical roller bearings When using spherical roller bearings, axle deformation can be compensated without additional force. FAG spherical roller bearings are used as wheelset bearings for freight cars, locomotives and other railway vehicles.

The axle box design is individually matched to the surrounding structure and optimized through BEM calculations. Ordering example: F-561860.ANM 130-T-AF: Schaeffler code 561860: Drawing number ANM: Axle box type 130: Journal T: Bearing type A: Quantity series Axle box split design Split design, after removing the lower box, the wheelset can be easily withdrawn from the bogie for maintenance. Another characteristic of the split axle box is the material used. Austempered ductile iron (ADI) has the advantages of high strength, good toughness and light weight. The use of this material makes it possible to manufacture compact, lightweight axle boxes. Wheelset axle box Z-176548.ASZ160-Z-*The main box is a general part. The delivery form of the axle box Z-176548.ASZ160-Z-* depends on the different designs of the end caps. It has been painted before leaving the factory and can be installed by the user immediately. The ductile iron axle box is fully quality controlled according to EN1563 and additional component testing. In addition, the axlebox body is calculated and optimized to meet the application requirements by means of modern structural analysis methods. The axle box bearing adopts double row cylindrical roller bearing F-801804.ZL with plastic steel cage and sealing cover.
