Air Bearing Linear Stages

We offer a wide variety of ultra-precision linear air bearing stages for the most demanding motion applications such as linear straightness measurement, linear positioning, high velocity scanning, constant velocity and applications requiring no static friction. Available in hard-coated aluminum, hardened stainless steel, granite or ceramic depending on the application. Available with linear motor, encoder, and drive amplifier to a full turn key solution. ABTech’s modular design and full engineering services allow us to respond quickly with a solution to your OEM needs.

Oil Hydrostatic Linear Stages

Oil Hydrostatic Linear Stages are 4 times stiffer than an air bearing of equal size; these linear stages are ideal for the most demanding high precision machine tool applications. If extreme stiffness and high load capacity are key to your application, ABTech will help you select the right oil hydrostatic stage. Our systems include the Hydrostatic Power Unit (HPU) which consists of a low speed precision pump, pressure sensor for closed loop operation, filtration system, and reserve tank.

Mechanical Linear Stages

When air bearing level precision is not needed, ABTech offers a wide variety of precision mechanical bearing stages. These offer a high load capacity and stiffness with straightness accuracy to 40 µ” (1 micron) or less per inch of travel. Ideal for low speed measurements, inspection, precision assembly or point to point positioning. Available in a variety of size, travel, and motor drive options.
