For all you prop gurus out there...

A ran across this drawing and something struck me as odd... why is the
prop blade only being held in with one bearing? Wouldn't it want to
rotate about this bearing slightly and put a lot of force on the pitch
change mechanism?

Or in other words, why isn't the blade held rigidly?
