Diesel and electrical units

In passenger transportation, more and more electric and diesel multiple units are used for long and short distance service, especially where shorter trains operating with shorter intervals are needed. In addition, there are trains composed of one or two locomotives and passenger coaches. These coaches can be designed as sleeping or restaurant cars.

The vehicles are equipped with either tapered or cylindrical roller bearing units. To achieve a lower mass and reduce energy consumption, light designs are preferred. This also influences the design of axleboxes. Because of the different bogie designs, various axlebox designs are needed to fulfil a typical customer’s specifications. SKF offers a unique package comprising axleboxes, AXLETRONIC sensors, bogie condition monitoring systems and wheel flange lubrication systems plus service engineering support including remanufacturing options.
