Absolutely Reliable Signal Transmission in Space Applications

Rotary joints made by SPINNER for use in space make a decisive contribution to technological progress and precise communication because satellites in outer space would be almost worthless if communication links with ground stations were not permanently maintained.

The antennas of satellites have to be permanently targeted at their ground stations, a task for which rotary joints are indispensable. Space, however, presents one of the most extreme environments for our products, demanding the highest levels of reliability, precision, and quality. The severe temperature fluctuations in orbit place immense stress on materials.

For many years, our Rotating Solutions division has been developing and manufacturing space-qualified rotary joints and other components. Leading companies worldwide rely on our innovative products and tailor-made, top-tier solutions for satellite antenna tracking systems. With over 700 units delivered in recent years, we have gained extensive experience in producing rotary joints for extraterrestrial applications.

Superior Rotary Joints for Space

For rotary joints implemented in space applications, SPINNER designers use special materials that combine low weight and perfect durability. One example are the lubricants used in the bearings, which need to withstand these loads and to be approved for use in space.

Even under the extreme conditions in outer space, a rotary joint has to ensure absolutely reliable signal transmission over the whole service life of the satellite. In addition the lowest possible weight plays a key role.

The wealth of experience that our engineers have with rotary joints in extraterrestrial use and our commitment to continuous product improvement are the basis of our great success. When it comes to application in space, all major customers in Europe already trust in our rotary joints

Test Capabilities

To guarantee the best possible quality of each product, SPINNER offers a wide range of tests.

The requirements and procedures for all testing is specified according to customer needs. Most tests are performed in house, for others SPINNER does cooperate closely with space qualified laboratories close to the SPINNER Westerham site.

Examples for Possible Testing Include:

Dimensional Check
RF Measurements
FEM Analysis
Thermal Cycling
Shock & Vibration
Thermal Vacuum Test
Additional Test available on request
