Nelson
Air's flat pad air bearings are offered in a variety of sizes, shapes
and load capacities which can easily be used to create custom air
bearing systems. Flat pad air bearings operate on flat, nonporous
surfaces such as granite, aluminum, glass, and ceramics.

In addition to round flat pad air bearings, Nelson
Air has supplied a number of rectangular flat pad air bearings.
These bearings are useful when the envelope of the system requires
constraining the size of the air bearing in one direction but the
load is larger than a round pad will support. In addition, long
rectangular flat pad air bearings can resist moments and take the
place of two round flat pads.
To learn more about rectangular flat pad air bearings
and how they can fit into your application, please contact
us.

Vacuum
Preloaded Flat Pad Air Bearings |
|
|
|
When flat pad air bearings are used in lightly loaded applications,
it is common to use a vacuum preload. A vacuum preload allows the
bearing to operate closer to its design loading and therefore optimal
stiffness is obtained. Vacuum preload also allows the bearing to
resist light pull forces. Any flat pad air bearing can be modified
for vacuum preloading and tailored to your exact application. Contact
us for more information.

Custom
Flat Pad Air Bearings |
 |
|
 |
Although our standard flat pad air
bearings can be used in a variety of applications, it is often beneficial
to modify their design for specific applications. Working from our
extensive catalog of designs, custom shapes, sizes, load capacities,
and mounting options can be created in very shot time and at very
little additional expense from the standard models. We will gladly
help you design your configuration and mounting scheme to optimize
bearing and overall system performance. Please contact
us for more information. |
