Oil-Free Technology, Gas and Foil Bearings for High-Speed Rotors
Aerodynamic foil bearings demand more than standard engineering knowledge: rotordynamics, thermomechanics, micro-manufacturing – every discipline must be mastered. SADAP combines this expertise and delivers oil-free bearing systems for fuel cell compressors, micro turbines, and high-speed drives that run precisely and reliably even under extreme conditions.
SADAP Bearing Technology at a Glance
Your Partner for High-Performance Air Bearings – From Simulation to Series Production
Reliable Performance from the First Prototype
Experimentally validated simulation tools deliver reliable bearing parameters before the first prototype is manufactured. The result: shorter development cycles, fewer iterations, and a design that works from the start.
Validated Reliability Under Extreme Conditions
High-precision measurement technology and demanding test scenarios ensure that your bearings operate reliably even at extreme speeds, temperatures, and dynamic loads. Validation happens before you go into series production.
Custom Bearings for Your Application
Every machine has different requirements. Through systematic parameter variation, lift-off speed, damping behavior, and stability margins are optimized precisely for your specific application – for maximum performance without compromise.
Applications for Air and Foil Bearings
Turbomachinery
Turbines, compressors, and turbochargers operating at speeds up to 200,000 rpm and temperatures exceeding 300 °C – oil-free, maintenance-free, in continuous operation.
Energy Technology & Hydrogen
Fuel cell compressors, micro turbines, and ORC systems benefit from contamination-free air lubrication – ideal for hydrogen and clean gas applications.
Aerospace
Engine APUs, cabin compressors, and gyroscopes require maximum reliability at minimum weight – foil bearings meet these requirements without oil supply.
Medical Technology & Precision Equipment
Dental drills, centrifuges, and diagnostic systems demand low-vibration, contamination-free operation – gas-lubricated bearings deliver exactly that.
