I had a Heat pump that was making noise while it was running.
Old Keeprite unit that was about 10 years old and I pulled the little cap off, on the top of the fan, and put some grease in it...
Quieted right down and lasted another 22+ years(33+years total).
The furnace blower motor, of the same system, was replaced by me. When I installed the replacement blower motor I added a tube to access the bearing closest to the fan in the squirrel cage.
That motor ran over 25years..That motor got saved when we upgraded the furnace.
Used it as a portable to ventilate areas we were working...In an emergency I was used it in our guest house, when we needed one to get us by till the new one arrived...it eventually died..but I had the new one on hand..
Lube is important, should have access built in to all electric motors, but we need to keep the economy going so it isn't.
OhAsus changed my RMA email to the new serial number..Just have to follow throughKeep you posted!
