Title: 4mm motor shaft with D-shaped key
Post by: apluscw on April 29, 2013, 06:41:41 PM

Any suggestions where I might find gears that fit a 4mm diameter shaft with D-shaped key feature?

THX!

This link makes all kinds of gears.

These would work, just tighten the set screw on to the flat side of the D on your output shaft.

If possible find one that works here, as they help sponsor this site.
