Nelson
Air's linear air bearings provide smooth, accurate linear motion.
Choose from just the air bearing with the 100B to 1200B series rectangular
air bearing slides, or get a complete integrated positioning package
with the Atlas series of linear motor stages. If you require longer
travels and light loads, Nelson Air's extended travel air bearings
offer up to 64" of travel and do not require expensive precision
surfaces for support.
Standard
Rectangular Air Bearings
Offered in a variety of sizes, Nelson Air's standard rectangular
air bearing slides are the workhorse of the air bearing industry
and have been delivering trouble-free performance to our customers
for many years. They can be found in a wide array of applications
ranging from tensile testing to precision positioning.
Features:
Load Capacity from 30 lbs. to 2260 lbs. (@ 80 psi supply)
Standard travel from 2" to 36" (Custom travel up to
50" available)
3 Accuracy grades
Inherently frictionless/stictionless
Material: Hardcoat Aluminum, other materials available
Air pressure supply from 40 to 80 psi - low air consumption
means you can even use a stand-alone nitrogen tank
Longer/shorter and multiple carriage systems available
Bearings can be combined for multi-axis positioning
English and metric units available

Slide can be crowned
to compensate for deflection due to gravity
Extended travel air bearings are ideal for high speed, high accuracy,
lightly loaded applications. Unlike other long travel air bearings,
the bearing slide is supported only on the ends (similar to a gantry)
reducing the requirements for expensive precision support surfaces.
Inherently frictionless air bearings eliminate heat generation due
to friction, reducing "warm-up" time and thermal errors.
These bearings are ideal for integration with linear motors and
optical encoders for a total "non-contact" positioning
package.
