Roundness/Cylindricity Measurement

Roundtest RA-2200 Series

Product Information

ROUNDTEST RA-2200 Series is a Roundness/Cylindricity Measurement System.



  • All models are equipped with a highly accurate turntable that enables simple and accurate centering and leveling of the workpiece, which account for the majority of the essential setup work for measuring roundness/cylindricity.
  • Integrating the system vibration-damping platform has reduced the installation space by approximately 20-40% compared to Mitutoyo's earlier installation platforms. Additionally, a design with increased layout freedom greatly improves the measurement room utilization rate and measurement efficiency.
  • A safety mechanism is incorporated into the detector unit area. A collision sensing function has been added to the detector unit (when it is in the vertical orientation) to prevent collision in the Z-axis direction. Additionally, an accidental collision prevention function, which stops the system when the detector unit displacement exceeds its range, has been added. When an accidental touch is detected, the dedicated analysis software (ROUNDPAK) senses the error and automatically stops the system. 
  • The table provides high rotational accuracy (radial 0.02+3.5H/10000 μm; axial 0.02+3.5X/10000 μm), enabling the system to measure flatness and other characteristics, in addition to roundness/cylindricity, at a level that suits any application. For centering and leveling support, you can select either the A.A.T. (Automatic Adjustment Table) or D.A.T. (Digimatic Adjustment Table).
