ENSURING SUCCESS OF AEROSPACE & DEFENSE MISSIONS 

WITH

INNOVATIVE BALL BEARING SOLUTIONS

aerospace & defense missions can no longer be dependent on ball bearing failurE

Ball bearing is without doubt one of the most widespread mechanical components. 

But when a ball bearing is subjected to high speeds, heavy loads or a harsh external environment, its behavior remains misunderstood.

Under these extreme conditions, bearings may become unstable or deteriorate. Many space missions have been disrupted or even aborted, precisely because of bearing performance problems, with very serious consequences in scientific, technical, political and, above all, financial terms. Under such conditions, classical approaches to engineer or select bearings do not work.

The common feature of most bearing damages is the kinematics of the balls.

However, this kinematics is difficult to understand and to model accurately. In fact, it had never been properly described to date.

WE DID IT.

In particular, with the BUTTERFLY Cage, we have solved the CAGE INSTABILITY PROBLEM, encountered in turbopumps, RWA, gyroscopes, ... (and in many other applications outside the aerospace sector such as machine-tool spindles and turbomolecular pumps for instance) to which no fully satisfactory response has been possible for more than 50 years (patent pending). 

We have also engineered the COBWEB Bearingthe most precise high-speed bearing ever, which finds applications in various industrial sectors, ranging from turbopumps of rocket launchers to dental handpieces.

À propos

WE WORK WITH:

 

  • SPACE AGENCIES

  • SATELLITE LAUNCH COMPANIES

  • AIRCRAFT MANUFACTURERS

  • EQUIPMENT MANUFACTURERS (REACTION WHEELs, gyro's, TURBO PUMPS, ...)

  • defense contractors

Based on an original kinematic and power based analysis (and related unique tools), APO-GEE is able to accurately and completely characterize the movement of the balls within a bearing, and model the complete equilibrium of the bearing.

We can therefore analyze the phenomena specific to your applications in depth, provide tailor-made solutions, and thus ensure the performance and the reliability of your aerospace and defense mechanisms.

OUR innovative products ALSO solve TECHNICAL CHALLENGES IN OTHER SECTORS :

  • THE MACHINE-TOOL & SPINDLE INDUSTRY

  • THE AUTOMOTIVE WORLD

  • THE MEDical TECHNOLOGIES

  • ...

 

Contact us now, we will dive into your projects to see how to make them even more successful.
