Are you feeling friction in your vehicle test set-up?

Testing systems are used extensively in the automotive industry. The challenge is: How to prevent friction from affecting test systems and results? Applying the right motion technology in vehicle test systems is critical for obtaining uncompromised performance optimisation. Frictionless motion and positioning is the solution for precision results.

Benefits of air bearings for test set-ups

Zero friction

Results in infinite resolution and very high repeatability.

No noise or vibrations

Non-contact zero wear ensures consistent performance and no noise or vibrations.

High speeds

Air bearings can reach high speeds and high accelerations with minimal heat loss.

No oil lubrication

Eliminating oil problems. They are self-cleaning by positive air pressure.

Straighter motion

Air bearings are not directly influenced by surface finish and irregularities

Digital design

To test the performance in a virtual environment upfront.

Non-contact air bearings are ideal for various high speed, precision motion and positioning applications in vehicle testing.

Aerodynamic & wind tunnel testing


When testing (race) car aerodynamics in windtunnels, it is essential to simulate on-road conditions. High pressure air bearings in moving ground systems (rolling roads) avoid upward suction of the belt in areas of rapid air movement and guarantee zero friction between belt and bearing. The air film stabilizes and cools the belt and thus reduces the drive power needed for the moving ground system.

Tyre testing


Understanding the conduct of tyres and tyre mechanics is key in determining their influence on the ride, handling and safety of sport cars and commercial vehicles. Tyre testing is critical to conform to legislative requirements and to improve the overall tyre performance. Test set-ups with ultra high pressure air bearings (up to 25 bar) ensure friction free testing supporting high forces.

Drive train testing


From R&D to manufacturing and compliance testing, measurement of powertrain not only requires progressively greater accuracies but also consistency in measurement over the specified ranges and conditions. Non-contact air bearings guarantee friction free rotational motion for torque test systems and bearing & seal measurements.

Acoustic testing


The volume and noises emitted by assembled vehicles are the result of complex interactions. They vary during different movements in different conditions. Tuning out unwanted noise, vibration, and harshness requires sophisticated test equipment. Noise emitted by air bearings is close to zero, making them ideal as silent motion systems in sound-proof chambers set-ups.
