## Overall (mm)

| length | width | height |
|---|---|---|
| 60.0 | 60.0 | 18.0 |

**Exact dimensions.** True size, with no printing tolerance added.

## Notes

- Ø60 wheel whose top face rises and falls twice round the circumference, z = 14 + 4 sin 2θ (10 to 18 mm high), and is level along every radius, so a roller with a radial axis rests on it along a line. Ø8 bore; lofted through sections every 2°, within 0.001 mm of the formula.

|---|---|
| outside Ø | 60 mm |
| top face | z = 14 + 4 sin 2θ |
