| | Because of their non-contact nature, porous media air bearings provide advantages that traditional rolling element bearings, or even conventional orifice air bearings, inherently cannot. Here you'll find the performance of porous media air bearings compared to that of conventional rolling element bearings across eight critical characteristics. |
|  | This one-minute technology comparison shows that, unlike conventional rolling element bearings, porous media air bearings offer a non-contact solution, almost entirely eliminating stiction, thereby providing almost infinite resolution and repeatability.
1:00 (No Audio) |  |  |  | |  | Rolling element bearings, over time, show wear from mechanical contact, resulting in inconsistent machine characteristics. This short animation shows that with porous media air bearings there is no contact, so there is no wear, just consistent performance.
0:41 (No Audio) |  |  |  | |  | This concise animation shows that , without the contact or competing forces present within the raceway of a conventional rolling element bearing, porous media air bearings provide smooth, silent motion.
0:49 (No Audio) |  |  |  | | | This animation shows that porous media air bearings, which feature no contact and no internal moving parts, provide speed capabilities an order of magnitude greater than that of conventional rolling element bearings.
0:33 (No Audio) |  |  |  | |  | This quick animation shows how the rotating inertia of the balls in a conventional rolling element bearing limits the acceleration capabilities of that solution, in contrast to the non-contact, high-acceleration solution that porous media air bearings provide.
0:41 (No Audio) |  |  |  | |  | Porous media air bearings ride on a cushion of air so, as this animation shows, unlike conventional rolling element bearings there is no need for lubricant, and no resulting lubricant migration or out-gassing, significantly reducing maintenance.
0:41 (No Audio) |  |  |  | |  | The balls in a rolling element bearing create unwanted motion in all directions. This animation shows that with porous media air bearings there is no contact or internal moving parts, so there is no unwanted motion.
0:45 (No Audio) |  |  |  | |  | This nifty little animation shows how the momentum of the balls in a conventional rolling element bearing often amplify deviations in the guideway, while porous media air bearings actually average them, keeping linear motion true.
