Without knowing exactly how that shaft is loaded I wouldn't suggest using the 7/8 OD bearing. If they knew that the shaft was well bellow 40lbs load they could use the 7/8 OD bearing, but it's not difficult to design around a 1.125 OD bearing and bearings are not somewhere to cut corners on, I would never use that 7/8 OD hex bearing on a cantilevered output shaft.
