ABTech’s standard line of high precision, air-bearing rotary tables (AT Series) and heavy-duty rotary tables (HDRT Series) are ideal for low-speed TIR measurements, optical inspection, precision assembly, or light machining and grinding where radial and axial accuracies down to 2.0 µ” are required. These are available with tilt and center worktables, precision fixtures, 3-jaw chucks, vacuum feed through the center, and motor drives. They are manufactured with 440CSS and hardened to 58 – 60 RC, making these rotary tables the most robust available.

Rotation tables with air bearings are used when rotary motion with the highest accuracy, smoothness, and geometric performance is required. Due to the lack of friction, these high precision rotation bearings and direct-drive motorized rotary tables can achieve angular resolution in the sub-microradian range. PI’s air bearing design and manufacturing group provides hundreds of man years of design experience along with the manufacturing and test equipment to produce high quality rotary tables with the tightest tolerances.

Rotary air bearings (air bearing spindles) are friction free, and all of PI’s motorized air bearing rotation stages employ closed-loop, non-contact 3-phase direct-drive torque motors, and optical high-resolution rotary encoders for ultra-reliable maintenance-free operation with basically unlimited service life.

Absolute angle-measuring feedback sensors are available to provide closed-loop control with single digit microradian bi-directional repeatability. Direct-drive rotary air bearing tables also provide better eccentricity, flatness, and minimized wobble compared to rotary stages based on mechanical bearings. The friction-free design allows for high angular velocity without vibrations and noise.

Applications of rotary air bearing spindles / motorized direct-drive rotary tables include indexing, metrology, optical lens testing, bio-medical engineering, runout measurements of machined parts, and fiber optics.

PI’s high-performance closed loop servo motor controllers are available to precisely control position, acceleration and velocity, with advanced algorithms. Fully integrated multi-axis motion systems with linear air bearing stages and combinations with gantry systems are also available from PI’s air bearing division.

They come with worktable diameters from 4–24 in. (100–605 mm) with radial and axial accuracies from 0.000,001–0.000,010 in. (0.025–0.25 µm). Several models have load carrying capacities up to 1,000 lbs, and larger, heavy duty models can be supplied with air float centering assist or air/ball bearings. These heavy duty tables offer load capacities to 5,000 lbs and diameters to 60 in. (1,524 mm).

The modular design allows the rotary air bearing tables to be used in a variety of measurement and motion applications. They can be used with the company"s line of options and accessories.

These systems designed to replace conventional compounded XY tables, where one axis is being carried by another. As a result, Planar XY Table offers greater reliability and performance realized through design simplification and elimination of wear-prone components.

Planar XY Table consists of moving element called forcer which glides on the frictionless air bearings over the special "waffle-like "surface called platen.

PI Nelson Air has developed an extensive catalog of rotary air bearings and air bearing tables for diverse applications such as optical grinding, roundness checking, disk drive inspection, semiconductor processing, torque testing, and many others. In addition to offering a line of standard air bearing tables, we can provide individually customized bearings for each application. When you call us with your rotary bearing application, we will quickly adapt one of our many existing designs to fit the exact requirements.

These high performance rotary air bearings are designed for accuracy, precision and ease of use. These air bearing rotation tables can be used in any orientation and are easy in integrate with motors and encoders for complete positioning solutions. We use them with simple o-ring belt drives for ultra-precision grinding and inspection in house. Please download a datasheet for more information.

The ABRT series precision rotary tables from Jena Tec utilise robust high precision roller axial bearings with an air bearing in the horizontal axis for smooth, precise rotary motion. The air bearing principle offers a compact overall height of only 100mm with a cost effective bearing solution and high geometric accuracy. A hollow shaft design means that centralised services for pnuematic or hydraulic clamping can be provided easily. Units can be supplied in either manual or CNC format with a standard range of torque motors offered.

Air Bearing Rotary Tables, Table Top and Work Load are Supported on Air Bearings whose Freedom from Friction Contributes to Extremely High Positional Accuracy

An Interlocking Switch is used when Motors are Incorporated to Prevent the Table Top from Moving when the Air Supply is Turned Off.  When the Air Supply is Turned Off, the Table Top Sits Firmly on our Cast Base with an Extremely High Accuracy of Parallelism Between the Base and Table Top

Rotary tables specifically developed for use in Metrology applications.  CMM tables, inspection tables, assembly tables.  Range of sizes 100mm thru 5,000mm.  Larger on request.

Air bearing rotary tables, when rotating, the table top and work load are supported on air bearings whose freedom from friction contributes to the extremely high positional accuracy.  High precision needle roller bearing maintains radial accuracy.

Air bearing stages are used where vibration-free motion is required, velocity needs to be highly constant, and optimum angular repeatability is requested.

Air bearings avoid friction, wear, and backlash effects. PIglide linear, rotary and spherical bearings are precision components that can be integrated and motorized for applications in OEM, industrial, and research markets.

The design of the ABRS series direct-drive rotary stage has been optimized to minimize stage height. The low profile of the stage reduces the effective working height of the system, minimizing "stack-up" related errors. In addition to the low overall height, the ABRS series provides a clear aperture that can be used for product feed-through, laser beam delivery, cable clearance or application-specific requirements.

The ABRS design features large air-bearing surfaces for high stiffness and load capacity, producing not only excellent axial and radial error motions but outstanding tilt error motion, as well. The resultant face error motion is significantly better than other rotary air-bearing tables and spindles, greatly benefiting applications requiring exceptional planar performance.

This is a high precisions rotary table/air bearing spindle made by Professional Instruments Company, Block-Head model 10R-15.
