AXRY-MI/MA Angle Measuring System

AXRY bearings can be fitted with inductive angle measuring systems. These systems are available in incremental (MI) or absolute (MA) versions, as single-head or multi-head systems with various accuracy grades.

By mounting the measuring ring directly onto the bearing ring, concentricity errors relative to the axis (table) are minimized, enabling the highest accuracies of a few arc seconds.

myonic supplies only "the mechanical part", i.e. the bearing including the mounted measuring ring, together with the threads in the outer ring for axial or radial mounting of the scanning head.

Key Advantages

High-Precision Measurement

With multi-head solutions, accuracies of +/-1 arc second can be achieved in practical applications

Inductive Technology

AMO measuring systems use purely inductive technology with no magnetic or optical components, providing resistance to electromagnetic interference

Direct Mounting

The measuring ring is mounted directly on the bearing, with no separate bearing required, enabling the largest possible hollow shaft

Open System

Measuring heads can be procured directly from Heidenhain (AMO), with no dependency on a single bearing manufacturer
