ABTech, Inc. Air Bearing Rotary Tables

ABTech’s precision air bearing rotary tables address the metrology needs for different weights and part size. Built for the most demanding applications, every table provides ultra-smooth motion, sub-micron accuracy and absolute repeatability. Designed and manufactured in-house to extremely tight geometric tolerances, air bearings have no mechanical contacting parts to wear or create drag. This allows for decades of reliable maintenance-free motion. ABTech’s AT models come standard with dual element filter/regulators and are commonly used as the core axis in equipment checking total indicator reading (TIR), roundness, flatness, squareness, perpendicularity, concentricity and parallelism measurements. They are ideal as stand-alone units for checking runout of turned parts, optical lens alignment, assembly applications, precision indexing, and light machining or grinding. The heavy-duty HDRT tables complete the product family. They are a perfect solution for large part applications. To speed part setup and increase productivity, the AT model tables come standard with our industry-best adjustable tilt and center (tip/tilt) work-tables. The tilt and center are optionally available on the HDRT models. We understand metrology needs often require operating in harsher environments. We use the most durable hardened 440C stainless-steel air bearing. This affords forgiveness from minor accidental touch downs that may result from low air pressure, excessive loading, or operator error. All rotary tables can be customized with a variety of options and accessories including motor drives, vacuum worktable (AT Series), high-resolution optical encoders, digital readout (DRO) displays, inspection-grade granite surface plates and gage stands. If our standard tables don’t fit your application, our precision motion experts will work closely with you to configure a rotary motion solution that will meet your exact needs.
