AXRY bearings can be fitted with inductive angle measuring systems. These systems are available in incremental (MI) or absolute (MA) versions, as single or multi-head systems with various accuracy levels.
By mounting the measuring ring directly onto the bearing ring, concentricity errors relative to the axis (table) are minimized, enabling highest accuracies of a few angular seconds.
myonic only supplies "the mechanical part", i.e. the bearing including the mounted measuring ring and thread in the outer ring for axial or radial scanning head mounting.
Key Advantages
High-Precision Measurement
With multi-head solutions, accuracies of less than +/- 1 arcsec can be achieved in practical applications
Inductive Technology
AMO measuring systems use purely inductive technology without magnetic or optical components, resistant to electromagnetic interference
Direct Mounting
Measuring ring mounted directly on the bearing, no separate bearing required, enabling maximum hollow shaft diameter
Open System
Measuring heads can be procured directly from Heidenhain (AMO), no dependency on a single bearing manufacturer
