Design Specification



1. Dimensional tolerance

Dimensional Range (DIM.) General Tolerance (TOL.) Special Tolerance (TOL)Special Tolerance (TOL)
1~12 mm ±0.2 mm  ± 0.13 mm
13~25 mm ±0.25mm ± 0.15 mm
26~50 mmm ±0.35 mm ± 0.2 mm
51~75 mm ±0.5 mm ± 0.25 mm
76~100 mm ±0.7 mm ± 0.3 mm
101 mm 이상 ±0.75% ± 0.35 %

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.

5. Roundness

Diameter Sum of measurements
0 ~ 12 mm 0.25 mm
13 ~ 25 mm 0.35 mm
26 ~ 50 mm 0.50 mm
Additional tolerances apply when more than 50 mm

6. Weight and size limits

2) Recommended dimensions of SLOT
만약 w > 3.0 mm (.120") 이고
ℓ>2w일때 ℓ<2w일때
h < 2w h < 3w
※ When h is less than 1.0 mm, the minimum value of w is recommended to be more than 1.3 mm (0.051 ")
