Conventional stages with rolling steel bearings exhibit friction and other mechanical nonlinearities; they are also dependent on servo-loop filters (including sluggish integrator terms) which all ...

This file type includes high-resolution graphics and schematics when applicable. Most motion applications use mechanical bearing guidance. However, there are many cases in which precision, angular ...

The accuracy of motion systems used in precision automation applications is significantly dependent on top-tier positioning stages and motion controllers. When designing a next-generation machine or ...

Seeing a heavy load slide around on nearly frictionless air bearings is pretty cool; it’s a little like how the puck levitates on an air hockey table. Commercial air bearings are available, of course, ...

This video shows the principle and advantages of air bearing stages. Air bearing stages replace mechanical contact by a thin air film, avoiding wear, friction, vibration, and hysteresis effects. PI's ...
