I imagine the spin-rate would keep a lot of gunk out of there...maybe.
Curious conundrum... Although the shaft would be spinning at a decent rate, the little bearings would only go through a tiny movement on each moment of contact, so they'd have a very slow rotation rate, making them somewhat more prone to binding or suffering impact effects from dirt caught between the meat-grinder.... oh, sorry, sprocket teeth and the shaft lobe bearings.
