3. Flatness and Straightness Equal to the above dimensional tolerances
4. Concentricity management
- Typical concentricity management within 0.13 mm (0.05 ") per 25.4 mm (1")
- The amount of shaking is reflected in the deviation of the straightness if the length exceeds twice the inner and outer diameters, respectively.

※ When h is less than 1.0 mm, the minimum value of w is recommended to be more than 1.3 mm (0.051 ") |
3) Avoid sharply reducing thickness
4) Designed for easy separation
5) Avoid sharp edges
6) Avoid angled corners
7) Embossing is recommended rather than engraving.
8) Designed so that the intersecting parts do not gather together
