NOTES:

1.  Above dimensions and tolerances are in Millimeters (mm).

2.  Tolerances shown represent total tolerance band. For example, a 50mm dimension under a CT5 tolerance (=0.5mm) means 50mm +/-0.25mm.

 

3.  Tolerances in the above table should be used as a guide only. Actual tolerances achieved may be looser or tighter, depending on specific tooling and casting features.
