Features & Benefits
Accurate, Repeatable, Smooth Motion
HDRT model air bearing tables are designed and built by ABTech for heavy-weight applications with weighted pre-loads and offer the following advantages:
- Frictionless and maintenance-free rotary table
- Ultra-precision sub-micron accuracy
- Nearly absolute repeatability
- Highly robust materials that minimize touchdown and gall damage
Requires standard compressed shop air (60 psi)
Manufactured with tight geometric tolerances, our standard air bearings deliver radial and axial error motion of <10.0 µ” (250.0 nanometers) and angular errors (coning) of 1.0 µ” per inch (25.0 nanometers/25mm).
Air bearings enjoy significant advantages over mechanical bearings or other approaches to precision worktables. Because there are no mechanical contacting parts to wear or create drag, air bearings are near frictionless, providing ultra-smooth, repeatable and maintenance-free motion.
Metrology is no longer relegated to the quality control lab. Maximizing productivity means exposing measurement devices to harsher environments within the production and assembly processes. To ensure you’ll experience years of service and investment longevity, we use only the most robust air bearing components. That robustness includes the ability to withstand minor accidental touch downs resulting from low air pressure or excessive loading. If an accident does occur, often the air bearing will only require repair rather than complete replacement.
Configuration Flexibility to Meet Your Specific Needs
Part of our “Pride in Precision” philosophy means providing you with precisely the solution you need. We don’t believe in selling our customers more, or less, than what their application calls for. With almost two decades of listening to our customers we’ve been able to develop a broad range of options and accessories to address the majority of ultra-precision measurement applications. (See options and accessories for a complete list.)
But no matter how broad our product options may be, we realize that they can’t address every possible application. And that’s what separates ABTech from most other metrology suppliers. We won’t say sorry, best of luck. Rather, we’ll connect you with one of our precision motion experts and work closely with you to configure a rotary motion solution that will meet your exact needs, including developing custom solutions for the most unique applications.
