Mechanical-Bearing Rotary Tables
ABTech’s line of precision mechanical rotary tables address the motion needs for a full range of part sizes and weights. High precision angular contact bearings are incorporated into stages that are designed and manufactured in-house to extremely tight geometric tolerances. The result is superior performance in radial, axial, and angular (tilt/coning) error motions.
Mechanical rotary tables are used in a wide range of applications and are ideal as stand-alone units and/or multi-axis assemblies, cylindrical part staging, TIR Inspection, for assembly and alignment tools, position measurements, optical scanning, light machining and grinding, and more.
Precision motion comes in many forms and applications, each with its own set of pertinent specifications. Diversity in today’s applications creates unique requirements, we provide configuration flexibility as an integral part of our design philosophy. All rotary tables can be customized with a variety of options and accessories. This includes motor drives, vacuum worktables, high-resolution optical encoders, digital readout (DRO) displays, inspection-grade granite surface plates, and more.
In addition to the options and accessories, material selection is a key focus of our applications engineers. For harsher environments, best accuracy, precision, and stability we use 440 hardened stainless-steel components. Focused on cost, ABTech will utilize the efficiencies of hard-coated aluminum construction. Our precision motion experts will work closely with you to configure a rotary motion solution that will meet your exact needs.
Features & Benefits
Superior Mechanical Motion
ABTech mechanical stages are superior in performance and quality. The key to high-performance rotary tables is in the geometry and quality of the mating components. By leveraging our knowledge and experience gained in producing the extreme tolerances required for air bearings, ABTech mechanical bearings achieve radial and axial error motion of < +/-25.0 µ” (+/-.63 micron).
Configuration Flexibility to Meet Your Specific Needs
Part of our “Pride in Precision” philosophy means providing you with the precise solution needed. We don’t believe in selling our customers more, or less than what their application calls for. No matter how broad our product options are, we realize they don’t address every possible application. Our precision motion experts will work closely with you to configure a rotary motion solution that will meet your exact needs.
