Pump shaft key measurements - typically measured from edge or center?
Pump shaft key measurements - typically measured from edge or center?
(OP)
On pump shaft drawings that list the depth of the key way is the depth measured on the sides or in the center. If measured in the center then the downward curvature would mean the edges would not be as deep. The drawing does not specify where the measurement is taken from. Is there a standard practice for what the depth is measured from?

Subtract that from the shaft diameter, and you've got a depth.

If verifying dimensions after machining is complete, do as explained above.
