Having never seen a BW wheel bearing set up its a little hard to understand from the description given the exact bearing set up used, however a single row tapered bearing can only support a thrust load in one direction as opposed to a double row tapered, a pair of single row tapered bearings installed opposing each other or ball which can be thrust loaded bi-directionally. This means that for a single row tapered bearing to be used singlely (without a second single row bearing installed in opposite direction) in a wheel bearing application there must be a mechanism to support thrust load in an opposite direction to which the single row tapered bearing can supqort, ie. a thrust block which slides over the diff pinion pin in the center of the diff which the machined end of the axle butts up against and prevents inward thrust movement of axle. Out ward thrust force is supported by outer race of single row tapered bearing which is held by bearing retainer/brake backing plate, that bolts onto end of axle housing. End float and preload are adjusted by shimming in general. Hope this helps..
