Wheelset bearing test rig

Wheelset bearings are exposed to extreme loads at the interface between the wheelset and the bogie frame and must meet a wide range of technical requirements. In order to ensure optimal adaptation to the respective operating conditions, wheelset bearings are developed in close cooperation between manufacturers and operators of rail vehicles.

RENK wheel set bearing test benches support this development in a variety of ways, from the individual component to the completely assembled bearing unit. The RENK | RDDS automation systems for test benches can be used to simulate complete route profiles in the automatic program and thereby diagnose the effects of all major influencing factors on the wheelset bearings. As the airstream cooling significantly influences the service life of the bearing greases, RENK wheel set bearing test benches are usually equipped with an airstream simulation system.

For example, wheel set bearing test benches from RENK can also be used to verify compliance with DIN EN 12082. Special test benches serve the pre-selection and the suitability test of greases and oils according to DIN 51819.
