Comprehensive reasons to use YRTCMI measuring system bearings

Extremely high machining quality

YRTCMI measuring system bearings allow precise, reliable angular measurement to be carried out directly in the bearing level. The installation situation reduces the positioning scatter band, which produces extremely high machining accuracy.

Incremental measuring method and data transmission

Analog signal 1 Vpp compatible with all relevant controls. The measuring device has a second distance-coded track to establish the absolute reference. The continuous analog voltage ensures the stable data transmission via slip rings.

Inductive operating principle

As a result of the reliable and fail-safe inductive operating principle, machine failures are prevented. Extremely easy to install and service the YRTCMI increases the machine availability. The axial head can be mounted without adjustment; there is no need for additional alignment of the measuring device.

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.
