Case Study

Bearings Going into Space

For many things out there, the sky is the limit. But not for us. With a mission to innovate and develop the world’s best performing bearings for industrial use, we have recently closed a successful collaboration with the Danish Nano satellite manufacture GomSpace

GomSpace is a company with a mission to be engaged in the global market for space
systems and services. Specialized in introducing new products such as components and
platforms. After a complex process and rigorous testing, CeramicSpeed is now a certified and approved producer of high-quality bearings for a new application - our handbuilt bearings are now qualified for use in aerospace technology.

For a bearing to perform and be certified for use in spacecrafts, there are a few crucial
attributes it needs to feature. Due to the harsh conditions in space, a bearing needs to
perform under demanding factors such as fluctuating temperatures, absolute vacuum
and the violent G-forces during a rocket launch. For this purpose, GomSpace has tested
and approved the CeramicSpeed Bearings to withstand these challenges, without
compromising the bearings’ life.

CeramicSpeed Bearings are matched with ceramic Si3N4 balls which have an extremely low thermal expansion coefficient. This makes them exceptionally well suited in environments where temperatures are expected to fluctuate between highs and lows, like they do in space.

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. During the three
years of development, our bearings have passed several difficult tests according to the
ESA (European Space Agency) requirements. To this day, the CeramicSpeed Bearings
are still running above the expected bearing life, concluding a successful project and
