I am selling two harmonic drives.  They are identical units.  Size is 25 and the gear ratio is 80 to 1. Both units are used but appear in good shape.

The pictures are of the two units.  One unit has 14 in the name.  The other unit has 18 in the name. Both units are matched sets.

Part numbers are:
Ring: 25-80-371
Cup: 25-80-362
Eccentric: 25-80-372

Price: $125 per drive
