| Order No. | 177-434 |
|---|---|
| Nominal size ød (mm) | 45 |
| Dimensions (mm) øD | 85 |
| Dimensions (mm) øE | - |
| Dimensions (mm) T | 15 |
| Type | A |
| Tolerance between the nominal size and the actual diameter (μm) | ±10 |
| Uncertainty of marked diameter value*¹ (μm) | 1.5 |
| Roundness / Cylindricity*² (μm) | 1.0 |
| Distance from the side face H (mm) | 3.7 |
| Size of warranted calibration surface K (mm) | 7.6 |
*1 Actual diameter is marked in 0.001 mm increments. (Dimension measuring position is the center of the height T.)
*2 Cylindricity is defined as per JIS B 0621 Definitions and designations of geometrical deviations, Section 4.4 “Cylindricity.”
Cylindricity is measured using three cross-sections between the top and bottom face of a ring, namely, close to the face near each side and the center.
