I would have assumed that was a monster bearing. Surprised to hear it is standard duty. I was always baffled by the whole single-sided swing arm deal.

We have a lot of mills here, and our local bearing supplier services them and helps diagnose bearing failures. One of the employees teaches this class at our community college, and I jumped at the chance, very interesting.
One semester, all about bearings.
My Airhead has two tapered roller bearings on the rear axle, PLUS the main bearings supporting the final drive bevel gears. I do not remember hearing of one ever failing.
