Reaction wheels are critical to satellite attitude control, where even minimal friction or vibration can affect pointing accuracy. In our collaboration with Space Inventor, we supplied customized hybrid bearings designed specifically to meet the demanding requirements of modern satellite platforms.
Reaction wheels require:
- Ultra-low friction to minimize energy consumption and ensure smooth rotation
- Minimal vibration for high-precision pointing of sensors, antennas, and optical instruments
- Vacuum-stable materials and lubricants that do not degrade in orbit
- Dimensional stability under extreme temperature fluctuations
CeramicSpeed hybrid bearings meet all these criteria, delivering the reliability, stability, and long operational lifetime that reaction wheels depend on. In Space Inventor’s compact CubeSat systems, our bearings demonstrate how low mass, high precision, and exceptional durability enable world-class performance in orbit.

Supporting Technologies Across Aerospace
Our experience with highly demanding aerospace applications—such as jet engines, landing gear, auxiliary power units, and actuators—strengthens our ability to engineer bearing solutions that perform under heat, load, vibration, and intense G-forces. These same capabilities translate directly into the needs of reaction wheels operating in vacuum and through extreme thermal cycling.
Commitment to Quality and Precision
Every CeramicSpeed bearing undergoes rigorous testing to ensure long-term reliability. Our advanced materials, coatings, and engineering expertise allow us to tailor solutions for even the most sensitive reaction wheel assemblies. The result is a low-energy, highly stable component designed for missions where failure is not an option.


Through the course of three years, we have tested a series of material combinations and designs that have now converged into a customized ceramic hybrid bearing solution, specially designed to answer the challenges of aerospace technology.
