They are pigs to fit and remove if a tight fit.
They stop the crank from moving fore and aft at the back end which may be an advantage as the rear race takes the clutch thrust rather than bending the crankshaft every time you press on the clutch.
My last one brinneled its balls, luckily no damage elsewhere from flakes of ball bearings.
Do not expect to be able to draw the steel housing out using the threads in it you will have to drift the bearing out from inside the crankcase carefully.
And yes no rear main grumble using these bearing.
