Umbra has been designing and manufacturing precision ballscrews and high precision components for the aerospace industry for over 35 years. Umbra has quickly become the global leader in aerospace ballscrews technology after being contacted by The Boeing Company, already a customer for the 747-400 flap ballscrews, to work together with BCA to solve look-out in service, premature wear and corrosion problems on flap ballscrews just over two decades ago. The problems were solved by introducing a new CRES steel (Cronidur 30) for the screwshaft and ballnut, ceramic (i.e. silicon nitride) balls and more efficient seals.. Today, there is an Umbra part that powers a flight-critical control surface on every single Boeing commercial aircraft rolling off the Seattle and Charleston assembly lines.
Moreover, Umbra now supports 18 global aircraft manufacturers (Airbus, Alenia-Aermacchi, AVIC, BAe, Boeing, Bombardier, Cessna, Dassault, Embraer, Eurofighter, Fokker, Gulfstream, JDA, Learjet, Lockheed, Mitsubishi,Panavia, Pilatus) and over 60 military, commercial, regional, and business jet aircraft programs in addition to UAV and guided weapons programs.
Umbra has quickly developed a reputation for eliminating corrosion, reducing wear and dramatically extending the service life of machined components including ballscrews, acme screws, safety rods, precision shafts and gears that serve as the mechanical heart of electro-mechanical systems powering primary and secondary flight control surfaces, and high lift systems in commercial and military aerospace today.
Remarkably, even after some of Umbra’s products have been in demanding commercial airline service for more than a decade, they remain within the original manufacturing tolerances. This “fit and forget” advantage reduces maintenance costs, dramatically lowers product life cycle costs and makes aircraft relying on Umbra innovation and technology less costly to operate for the final customer.
The key to Umbra’s success is its constant and substantial investment in research and development, coupled with its ongoing manufacturing and process improvements. Weather it is as a result of breakthrough designs or manufacturing efficiency, Umbra continues to lead the way in the global aerospace linear motion sector.
