The Evolution and Impact of Free-Flex® Pivot Technology: From Aerospace to Modern Innovations
Like most of the world's engineering marvels, the Free-Flex® Pivot design started as a question: What can we use to produce a gimbal ring with precise, repeatable motion in multiple axes at small degrees of rotation? In early 1960, Henry Troeger answered that question — and a new class of bearing was born.
Precision Movement and Repeatability: Original Innovation
Through the use of an intercrossed dual-spring system encased within a cylindrical housing, Henry Troeger created a bearing that had never before been seen. The Free-Flex® Pivot provided a new way to incorporate rotational motion — allowing for precision movement and repeatability the likes of which had never been imagined. It quickly opened up new possibilities for applications that had previously seemed unsolvable.
The Evolution of Free-Flex® in the Aerospace Industry
News of the new solution for precision rotational motion spread quickly. The Free-Flex® Pivot began to blossom as a solution to many issues in the aerospace industry. NASA took notice and used the product extensively across numerous space applications — publishing papers on how it could be implemented into both existing and new designs as humanity looked to venture beyond Earth.
Whether in gimbal mounting systems for the thrust engines of the Lunar Orbiter or the delicate sensing and mirror systems of the Hubble Space Telescope, the Free-Flex® Pivot helped lift us from the confines of our sphere up into the final frontier.
Adaptation to Modern Industries
In today's landscape of ever-changing technology, the Free-Flex® Pivot has continued to remain a titan in the space of rotational movement through adaptation to new and improving industries.
Semiconductors
Engineers have found the Free-Flex® Pivot to be a critical element in wafer-handling machines, where the ability to operate in a vacuum with repeatable, precise, and measurable motion is paramount.
Medical Technology
From MRI machines to remote surgical systems, the Free-Flex® Pivot has assisted medical professionals worldwide — enabling precise motion in environments where accuracy and repeatability are synonymous with success.
The Continuing Legacy and Commitment to Innovation
While adapting to new industries is often a requirement for survival, the Free-Flex® Pivot has not forgotten its roots. In the aerospace sector, engineers continue to rely on its unique movement capabilities for mirror mounting and positioning systems. Even 60+ years after its introduction, the Free-Flex® Pivot continues to aid mankind in discovering the mysteries of our universe.
Each and every day new applications arise where the Free-Flex® Pivot can be the best solution for the job. At Riverhawk, we approach each new application with enthusiasm and a desire to provide quality solutions to our customers.
