john deere 1780 planter disk problem-bearings?

We have replaced a number of disks on the units but the bearings seem to fail prematurely. We tried looser , tighter etc but do not seem to be curing the problem. The old disks do not seem to have any problem. What is going on? We tried alternate suppliers too. Thanks for any insight!
