New ZKL two-row tapered roller bearing unit for railway vehicles
It is used to store the wheelsets of railway vehicles. The bearing unit has polyamide cages and contains a special lubricant guaranteeing lower friction in the bearing with a positive impact on heat generation during operation. The added value of the whole project is the fact that the bearing units are assembled in trains of a European manufacturer, which will be operated on the territory of the Czech Republic within the framework of regional transport.
The maximum operating speed of vehicles using these bearings is 160 km/h with the maximum permissible axle load of 18.5 tons. The PLC 810-13.D.2 bearing unit meets the current requirements of the TSI and the EN 12080 standard and ensures maintenance-free operation of the train up to 900,000 km.
