Comprehensive reasons to use YRTCMA/YRTSMA measuring system bearings

Extremely high machining quality

YRTCMA/YRTSMA measuring system bearings allow precise, reliable angular measurement to be carried out directly in the machine axis, which produces extremely high machining quality and high machine availability.

Absolute angular data

The omission of the reference search leads to uniform start behavior for all axes in machine tools.

Inductive operating principle

As a result of the reliable and fail-safe inductive operating principle, machine failures are prevented and outstanding levels of machine availability achieved.

Integration of the angular measuring system into rotary table bearings

The required installation space is reduced, which increases the size of the available machining area and makes the space in the center of the axis available for power cables, data cables, and media supply lines.


  • Absolute angular position values
  • Inductive operating principle
  • Integrated into the bearing
  • Hollow shaft and free space in the center of the axis
  • Electronic interfaces: EnDat22, DRIVE CLiQ, Fanuc alpha, SSI+1Vss
  • Electronically compatible with all conventional machine tool control systems
  • Precise angular measurement and maximum positioning accuracy
  • Extremely high levels of control rigidity thanks to an angular measuring system integrated directly into the axis
  • High reliability
  • Functional safety
