Flange Bearings

I bought some china flange bearings from Princess Auto. They have grease zerks. Why? There is no way for the grease to get in the bearing. Only between the race and housing.

In my case I wondered the same thing.
I have one customer, a seed cleaning plant and often their shafts are bent. and then the grease gets a workout til the housing wears. The other thing that happens is the bearing sizes and then rotates in the flange, and it is run that way til end of season. I grow garlic commercially and just finished building a garlic cleaner, using PA flanges, and in this case, it will prevent rust between bearing and flange so I can replace the bearing without a fight.
