I do not think a pin would have zero bending moment. It would have zero rotational displacement around the two axes not along the pin axial direction, but in resisting this motion, a moment reaction would be generated. Only rotational around the pin axial direction would be allowed. You should be able to accomplish this with a revolute or cylindrical joint depending on whether the pin is a press-fit.
