Reducing friction torque in railway wheelset bearings: A relevant contribution to reduction of train energy consumption

Data-driven engineering at the component level boosts efficiency

Hidden inside the axlebox is a major source of energy loss: the wheelset bearings. Friction distribution and lubricant behaviour in these inaccessible components are hard to measure, yet they have a significant impact on overall fleet performance.

In this session, Jan Babka explores how advanced modelling makes friction visible before physical testing begins. By simulating real operating conditions and validating results through measurement, engineers can identify loss drivers and redesign bearings for lower friction. Learn how even small reductions in friction in components can translate into meaningful system-wide energy savings over time.

You’ll get a clear look at:

Seal concepts that minimize torque without compromising protection
Surface roughness and profiling optimization
Clearance choices and their impact on performance

Watch the recording to see how combining modelling, measurement, and smart design leads to more efficient railway solutions.

In this 30-minute Railvolutionary webinar, Jan Babka shows how advanced modelling and digital twin technology make it possible to rethink critical components from the ground up. By simulating real operating conditions and understanding complex interactions inside the bearing, engineers can identify hidden friction drivers and optimize designs before they are built or tested.

Minimized friction losses

Learn how sealing choices, lubrication, surface roughness, and material selection influence friction torque and how to reduce it without compromising protection.

Faster rail operation

Less friction keeps heat under control at high speed and frees up energy for efficient motion.

Longer service intervals

Explore how low-friction wheelset bearings extend service intervals and reduce maintenance efforts.

Model and measure performance

Friction in axlebox bearings is difficult to capture directly. See how SKF uses digital models and validation testing to analyse friction torque and optimize designs before deployment.
