Seriously, if your getting that short a life there is something going on.
What is your technique for driving in the new bearings?.
You should use a driver that will rest on the outer race (like a socket) refrain from getting pressure on the inner race.
Put your bearings in the freezer for an hour before installation......ideally you would heat the alumni bearing tube & they would drop right in....but with a glued stator & windings, I'll refrain from telling you to throw it in the oven at 300f :wink:
Always something.
Keep going....you are almost there.
With the most recent bearing, I carefully tapped it in with a rubber mallet and a socket on the outer race. I will freeze the new bearing and replace it using a socket as well. One thing I notice is that the magnet can has some forward/backward "play", as in, you can slide it back and forth within the bearings. Could that be a factor?
