If you are looking to prevent the shaft from sliding out in that direction, you can turn the far end of the shaft to 1/2" round (or 3/8" round) and use a 1/2" round (or 3/8" round) bearing on the inner plate. That, combined with a snap ring groove on the outside of the inner plate, will fully retain your output shaft.

Oh yea I don't even need that snap ring. I was not thinking when I put it there. It's been removed but I didn't feel like re rendering. The shaft is turned down on the back to 1/2 round and it's tapped so it wont fall off.
