Tolerance between the nominal size and the actual diameter (μm) | ±20 |
Uncertainty of marked diameter value*¹ (μm) | 2.5 |
Roundness / Cylindricity*² (μm) | 2.5 |
Distance from the side face H (mm) | 5.3 |

*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.
