Design World Articles Highlighting AST Aerospace Bearings:

Desgin World Jan 2022

Manufacturers in nearly every industry are increasingly raising performance expectations for rolling-element bearings while at the same time exposing them to operating and environmental conditions that, when extreme, can reduce the rating life by as much as 90%.

Design World April 2020

Component optimization is critical for manufacturers of propulsion systems used in unmanned, hypersonic vehicles. Air molecules separate at such extreme speeds and high temperature effects stress the vehicle, including its sub-systems and components. Robust bearing solutions must be utilized to achieve desired performance.
