If the bearing is a proper press fit into a pocket in the gear it'll be fine. It's located by the pocket and there is no side load on the gear to push it off the bearing. This is the same way all the shifting gears are located in a dog shifter.

EDIT: It's a 40 tooth gear correct? If you don't want to machine a pocket get a vex dog gear with the pocket already machined. Vex 40t dog gear part number 217-3417. If the .5 bearing it comes with is too big for the shaft, press it out and replace it with the same OD .375 bearing vex part number 217-2732.

Thanks for the suggestions. I have a few questions about the PEM nuts.
If there is no flange, how does it hold the tension force from the bolt?
Where can they be sourced?/Do you have any suggestions?
what are the tolerances like on the press fit?
