They are part of the equation. But no, they are not its primary mounting.

Out of curiosity, did you waterjet the bearing holes and bolt holes in addition to the lightening pattens?
This past year, we only waterjetted the lightening patterns and outer profile, and then did all the mounting holes and bearing holes by hand with a mill (DRO!)

We made multiple sets of plates with multiple different machining techniques. The ones pictured were waterjetted in their entirety. When the bearing wholes were too small, we brought them to size with a half round file.

The hex standoffs just reach around the 2"×1" rail of the wcd chassis and bolt to the bearing block on the other side. The two bolts to either side of the output shaft are also used the mount to the frame.

How did you manufacture? CNC mill or something else?

these plates were cut on a waterjet, but we have another set that was made on a mill.
