When designing these you will need to have the bearing flanges on the miter/bevel side to take the axial load into the structure. I would also recommend a thrust bearing, an Oilite bronze bearing is ideal for this application. The Bearing Flange is 1/16" thick, and the Oilite Bearings are normally 1/16" thick in this size range. So make sure to account for another 0.125" behind each gear.
