Linear Motion
Printer-friendly version
When you need ultra-smooth linear motion with micro-inch (sub-micron) accuracy, ABTech’s linear air bearing slides match your demands for precision performance in both motorized and manual operation.
Whether you’re searching for low or high speed, variable or constant velocities, single axis or stacked stage configurations, our linear axes meet and exceed the requirements for:
- Wafer scanning systems
- Computer-to-plate systems
- Pick-and-place production automation where precision positioning is required
- Linear, straightness and positioning measurement
- Highly precise machining and vision systems
- Ability to be customized to meet the most challenging motion and geometry applications
In linear motion, we offer three basic rail configurations; LAB-D dovetail series, LAB-R rectangular series and LAB-S square series, with the following options, accessories and accuracy classes:
-
Options
Hard-coated aluminum, stainless steel, ceramic or granite rails; aluminum or stainless steel carriages; fully supported or end supported rail mounting; fully constrained, magnetic or vacuum preloaded carriage designs; and vertical, horizontal or stacking configurations.
-
Accessories
High-resolution optical encoders (available with millions of counts per inch); centrally mounted direct drive brushless DC motors (with a wide range of motor, torque and load sizing); digital drive amplifiers and programmable controllers.
-
Accuracy Classes
A1 Accuracy Class: Straight and flat to less than 5.0 micro-inches/inch (0.125 microns/25mm)
A2 Accuracy Class: Straight and flat to less than 15.0 micro-inches/inch (0.375 microns/25mm)
Our ultra-precise dovetail, rectangular and square air bearing slides are built without mechanical contact parts. You can depend on them for:
- Long life, requiring no maintenance or lubrication
- Thermal stability (granite or ceramic rails recommended for the most thermally sensitive applications)
- Durability and strength (ceramic rails recommended for extreme sag resistance in end supported applications)
- Vacuum-rated compatibility for semi-conductor applications
- Low consumption of compressed air or nitrogen
- Ability to be customized to meet the most challenging motion and geometry applications
