High-Precision Hardware Solutions for Your Rotor Bearing Requirements

For the bearing of high-speed rotating light shafts under extreme operating conditions (very low/high temperatures), aerodynamic air bearings offer a solution with a variety of advantages. They are maintenance-free and feature low power loss and long service life. SADAP provides customized bearing sets in prototype, small, and large series, ensuring the highest precision. Our products are manufactured with very tight tolerances to guarantee optimal performance and reliability – a critical factor in the development of air and foil bearings.

Why are tight tolerances so important?
Air and foil bearings rely on lubrication with a gas medium, where the clearance height is extremely small. Even the slightest manufacturing deviations can significantly affect functionality, as precise clearance height is essential to ensure frictionless and efficient bearing operation. Therefore, SADAP places great importance on adhering to the highest manufacturing standards to ensure that even minimal deviations are avoided, allowing the systems to deliver optimal results in practice.

In close collaboration with our partners, we develop solutions that are not only technologically advanced but also economically tailored to your specific needs.

Adaptive Air Foil Bearing: Bearings optimized for a wide range of operating conditions

The innovative technology of the adaptive foil bearing was conceived for the first time by the Institute of Adaptronics and Function Integration at the Technical University of Braunschweig and a patent application was filed. In this technology, foil bearings are equipped with an adaptive interface, whereby the effective bearing clearance of the bearing is actively controlled by means of piezoelectric patch actuators and adapted to different operating conditions.

The main objective of the control is to obtain optimum lubrication properties in terms of stiffness and damping behavior at higher speeds and load capacity and effective frictional torques at lower speeds. The result is a bearing in operation that has the optimized characteristics of multiple bearings with different bore geometries in a single bearing. We are pleased to announce that the performance of the adaptive foil bearing has been demonstrated and published based on numerous analyses in theory and the experimental tests with first prototypes.
