Here at UNASIS, we have strong links with the top global manufacturers of satellites, launch vehicles and space components, alongside providing essential technical support. We have contributed to projects such as solar array gear box mechanisms, LOX turbo pumps and circulators, reaction wheels, and liquid methane pumps; this is only a selection of our work. We take pride in the fact that our products were successfully integrated into the Mars rovers ‘Space’ and ‘Opportunity’, as well as the ‘Cassini’ probe currently orbiting Saturn.

We are accredited to ISO9001 here at UNASIS, incorporating the requirements of AS9120 with flow-down from AS9100. We have ample capacity to supply all of your aerospace bearing and tooling needs, while ensuring global customer peace of mind with a first-rate service. We can also include AS9102 Aerospace First Article Inspection Reports for traceability of all raw materials and special processes, as well as full dimensional analysis.
We have extensive expertise in the quality and testing requirements to validate a fledgling bearing design project. Our experienced engineers use SolidWorks to design custom bearing solutions, specifically tailored to each mission.
Our cutting-edge proprietary bearing application software is used to determine theoretical bearing performance, allowing us to provide detailed reports. These not only better inform our customers, but ensure that vital design decisions can be swiftly validated too.
We can provide further in-depth technical assistance; with FEA analysis and our unique understanding of how to interpret your data to optimise mechanical performance, we ensure that customers receive a tailored experience to accompany their technical advice.
