I don't believe the cracked cycloidal disk has much to do with any load.
It almost certainly is because of the hole for the bearing in the center was too small, and pressing it in causes permanent stress in the cycloidal disk.
The big hint is the wide gap in the crack.
That gap shows how much the plastic was stretched when the bearing was pressed in.
Are you sure? yes | no
How much load were you putting on the joint? Only 3 pins actually transfer the torque per gear. If you don't like bearings or bushing why not try larger diameter pins. eg 5-8mm.
Yes, delete it
