I totally understand the sentiment, as I apply the same much of the time. In this case, I have no idea if the pump has replaceable bearings. I installed a new pressure switch when I put it in service, along with the Solberg air filters. I drain moisture from the tank, shut off the output, and kill the power at the pressure switch at the end of every day, and I change the oil once a year. Should the motor ever fail, I'll bolt on a replacement. Should the pump fail, I will rebuild it if possible, or replace it. The point to my posts in this thread are that it is a good consumer-level compressor; just buy it at the right price point.
EDIT: Zooming in on my photo above, it appears to have a Century motor. I can take a photo of the decal later. To be honest, I've never looked at it. I just stuck the compressor in the corner, plumbed it up, and put it to work five years ago.
