I'm convinced that it is dirt that finds it way into bearing. The dirt grinds away on balls and races. If checked from time to time you will catch it getting looser and looser. The AGCO bearing is not triple lip. We use BCA brand P_N WPS100TRC for 1" shafts and WPS103TR2C for newer machines with 1 1_4" shafts. Both these bearings have provision for relube but are not utilized in this case. I don't recall a single triple lip failing or getting loose yet. Good luck
