Bevel/Miter Gear Mounting Distances

This depends on what you are designing. If you are designing a swerve drive, yes, you need a thrust bearing so that the gearbox can support the robot weight. On the other hand, if all you are doing is turning the motor sideways then driving another gear or sprocket, or are transferring torque from one direction to another (e.g. a lobster drive), there will not be a significant axial load.
