Paul, in one picture of the exploded ROSS PSRU there is a picture of a 2 piece thrust bearing. So the Ross is for tractor driven props only. I see no other bearings in the output section.

There are variations in the Ross. some have the power taken out
of the planet carrier and in that case the planet carrier is fixed to the
prop shaft and the trust bearing would be behind or on both sides of
the planet carrier.

Ross PSRU's where used in pushers as well as tractors.
