The comparison between conventional rolling element bearings and porous media air bearings begins and ends with contact.
Contact, and the resulting high stiction, often causes the rolling element bearing to overshoot its mark. This causes resolution problems, especially with light loads over short distances.
New Way Porous Media™ air bearings are entirely non-contact, so there is no stiction. The result is that you then have almost infinite resolution, and the repeatability so critical to today’s high performance, precision systems.
