For increased positioning precision and load capacity at high speed, these bearings offer advanced motion control engineering.
For applications where pre-loading is difficult or impossible, vacuum preloaded air bearings (VPLs) provide the solution. Combining vacuum with air pressure, they offer advantages for a wide range of applications in a diverse group of markets and industries. By adjusting the vacuum and the pressure separately, the fly height and stiffness of these vacuum preloaded air bearings can be optimized.
Our vacuum preloaded line replaces a portion of the surface area of our flat round bearings with a region dedicated to vacuum pressure. This combination of vacuum and air pressure can be finely tuned to adjust the fly height and stiffness for superior damping. This means that only one flat guide surface is necessary instead of two parallel, flat guide surfaces as in opposed bearing preloading.
Incorporating vacuum increases positioning precision and enables high-speed linear motion. Stiffer air gaps combined with no contact motion means you have higher load bearing capabilities while eliminating the possibility of production stopping crashes.
