E-ABR250 Rotary air bearing stages

Short Description:

This series is meticulously engineered to consistently satisfy even the most stringent performance

requirements. At its core is an industry-leading, air-bearing technology that delivers nanometer-level error

motion performance with high stiffness and load-carrying capabilities.

•Simple, Straightforward Integration

•E-3R-NGfeatures an advanced bearing design that provides excellent stiffness and high load capacity, while

maintaining compact overall dimensions and reasonably low overall mass. This makes E-3R-NG ideal to use

as a component stage in multi-axis motion systems and precision turnkey machines. E-3R-NG stages can be

mounted with the axis of rotation oriented either vertically or horizontally

Can be mounted vertically or horizontally
•Design Features
•Delivers best-in-class rotational motion, helping you to optimize your high-precision process
•Minimizes axial-, radial-, and tilt-error motions, reducing the need for extensive post-processing of parts and
measurement data
•Provides generous load-carrying capacity without compromising on motion quality
•Integrates easily into precision systems and machines due to compact, lightweight form factor, as well as
horizontal and vertical mounting and load-carrying capabilities
