Designing reliable satellite systems comes with a set of unique engineering challenges. In space, rotating components must perform with extreme precision, despite exposure to highly variable temperatures, centrifugal forces, and the complete vacuum of the orbital environment.

Add to this the mechanical stresses of rocket launch and the need to minimize weight while ensuring the protection and reliable function of sensitive instruments such as communication antennas, sensors, and mirrors - and you have a task that demands uncompromising quality.

At CeramicSpeed, we have extensive knowledge and experience in configuring custom bearing solutions for space applications. A recent example is our collaboration with Space Inventor, a Danish aerospace company known for their innovative and compact CubeSats. When they approached us to optimize the bearings in their reaction wheels - a core technology used to control satellite orientation - we knew the requirements would be demanding.

Reaction wheels require:
• Low friction to minimize energy consumption,
• Low vibration to ensure precise attitude control,
• Vacuum-stable materials and lubricants to avoid degradation,
• Dimensional stability under wide temperature fluctuations.

Meeting all these criteria makes ceramic hybrid bearings a natural and effective choice. These advanced bearings offer outstanding performance in extreme environments, and their use in Space Inventor’s systems is a testament to the reliability and technical precision we deliver.

For over a decade, CeramicSpeed has contributed to high-reliability space systems, helping clients like Space Inventor push the limits of what's possible in orbit. Together, we prove that the right components make all the difference - on Earth and far beyond.
