What factors contribute to air bearing stiffness?

February 12, 2021 By Danielle Collins Leave a Comment

air bearing stiffness

According to the American Society of Mechanical Engineers (ASME), stiffness is: The capacity of a mechanical system to sustain external loads without excessive changes of its geometry (deformations). When we think of stiffness in traditional bearings with rolling elements, we’re typically considering the deflection of the carriage when a load is applied. For air bearings, […]
