The ideal location to install a rotary table measuring system is directly inside the bearing support, which allows a higher level of system accuracy to be achieved by means of a measuring system integrated into the bearing than with measuring systems that are mounted on the axis and are therefore remote from the relevant bearing support. The highly precise radial runout of the YRTSMA rotary axis bearing is utilized here.

Features:
 

• Absolute interface eliminates the need for a reference run
• Hollow shaft design leaves the space at the center of the machine free for other components
• Highly-dynamic and precise control loops are made possible
• Design envelope is reduced
• Construction and mounting are simplified
• Resistant to environmental influences, lubricants, and cooling lubricants
