Linear Air Bearings
Description:
Nelson Air's linear air bearings provide smooth, accurate linear motion. Choose from just the air bearing with the RAB 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.
In addition bearings and systems can be customized from our extensive catalog of previous projects.

Linear Air Bearing Products
RAB Series Standard Linear Air Bearings
Offered in a variety of sizes, Nelson Air's RAB series of 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.
Atlas Motorized Linear Air Bearing Stages
Atlas stages from Nelson Air are a fully integrated positioning solution. We have combined the highest precision air bearings with linear motors and optical encoders to deliver outstanding performance in an extremely compact package.
Extended Travel Linear Air Bearing Slides
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.
Planar XY Air Bearing Stages
For the highest precision applications, Nelson Air has developed a number of Planar XY air bearing stages. These systems use air bearings which ride directly on a granite or aluminum base. By eliminating the height stackup and overhung loads typical of stacked stage designs, planar air bearings achieve flatness of travel equal to or better than the actual flatness of the base. In addition, these systems have superior stiffness and load capacity. Finally, because the repeatability of air bearings is much better than mechanical bearings long travel systems can be calibrated for extremely high accuracies.
