Class A Roller Bearings

Can anyone on the list enlighten a couple of NWHS
members regarding how the first style of driving axle
bearings worked on the Class A?

I've looked at the photos in N&W Giant of Steam, but
still can't figure out how the arrangement transferred
the load from the frame through the bearing to the
drivers. The later style is straightforward, no
problem there.

Thanks for any help on this!
