Unless you use a water washable sodium type grease the problem maybe the motor dust getting into the bearing and only more often perhaps weekly greaseing to purge the bearing will solve that.

So, is the quality of the grease important much at all, or is it the weekly/bi-weekly greasing that matters more?
I get my grease wherever i see it, home depot wherever. I usually buy what is cheaper, but there are some greases that are 7 bucks for a tube, are they any better than the 1.99 tubes for this application?

Bruce is right. Your problem is undoubtedly contaminants that result in abrasive damage of the bearing. The solution is replacing the grease by purging new grease through the bearing or cleaning and repacking more often. The type of grease is not as critical as the maintenance schedule for this application. I've never heard of grease being formulated to resist abrasive damage. Now about the seals....
Litium is the most common "soap" type and will resit water wash out OK stay away from any sodium type they will wash out As said by Kresta and Me the interval is most important If you grease only monthly then go to weekly ans look at the "grit" that will be purged from the bearing.

Buy a grease that contains moly. Cat equipment requires 5% moly in the grease for the pins and bushings, but that might be too much if you have ball or roller bearings. If you have plain bearings, it'll be OK. Buy your grease in an auto parts store or heavy equipment supply that sells to excavating companies and other heavy equipment outfits. It may cost less, also.
Or, go to a lubes distributor and search their catalogs for a grease that better suits your needs. Buy a 10 cartridge case.

Thanks for the imput guys, i will grease it more often.
The bearing are fine until the red rubber ring wears, then crap gets in there.
Im not sure if grease will help the rubber or not.
I have a mixer apart in my garage right now, and it is a major pain in the rear to get the bowl off to replace the bearings...

With out a question Schaeffers 238 will exceed your app.,,,,,,,,,,,,OR Mystik makes a grease called tetra-moly,which will work fine,,,,Amsoil also markets a heavy duty grease with moly,,,,,,,myself I would use the 238 #2 Schaeffers as its a aluminum complex,,,,,,,,BL

Can the seal (red rubber ring) be replaced separately? Seals are ever-so-important to bearing life. They are a wear item and a consumable item. One can have the best metal and the best grease, but if stuff gets past the seal, then the party is over. I've seen some seal designs that have four seal lips!
You'll have to include seal replacement in your preventive maintenance schedule. I still think cheap grease with EP additives used more often should suffice in your application.

Moly (MoS2) will only help if the failure mechanism is from heavy loads. If the failure mechanism is from entrainment of abrasive particles - as I suspect is the case - then all the moly in the world won't help.
