MADE IN JAPAN QUALITY RUN-OUT GAUGE SYSTEM
|
For those who handle a large number of cylindrical parts (small diameter) For those who use V-Blocks For those with variability in measurement by workers |
 |
If any of those apply to you, why not install our RUN OUT GAUGE SYSTEM. |
■ Easy to measure concentricity by mounting your current indicator.
■ Three base length, three rollers and three carriers (incl. no carrier type), total 21 product configurations available.
■ Up to 2μ accuracy. Highly accurate measurement is possible. *Up to 3μm accuracy when slit roller (for small diameter).
■ Smooth measurement with grip handle and timing belt & pulley operation system.
■ Carrier with angle fine adjustment for easy zero-setting of measuring instruments.
Free movement in Z-direction enables measurement at the optimum position.
■ Equipped with work retainer for holding front and rear of workpiece and to enable measurement of axial run-out.

MEASURABLE WORK CONDITIONS
●OD Slit/ Flat roller type: φ4-30mm Slit roller (for small diameter) type: φ1-8mm
●Length: 5～80mm
●Shape: Cylindrical
●Reference portion of the workpiece must have enough length to clamp to the rollers.
*Measurement error increases at with increasing distance from rollers.
*Soft materials such as non-ferrous (aluminum) and plastics may deflect and cause measurement errors depending on the outer diameter and length.
