I have a spinning 3/8" brass shaft and it is in an alumimun housing. I don't like the idea of the dissimilar metals (brass and aluminum) riding on each other. I didn't have any brass tubing the correct size to make a bushing sleeve for inside of the aluminum housing but the item had to be fixed. In my searching I came across some .38 Special brass cartridge cases. Their outside diameter was 3/8" so they were pressed into the aluminum housing and trimmed flush. They made a perfect brass sleeve for the aluminum housing. They were bored to 0.350" internal diameter. I then turned the brass shaft down to 0.348" and now I have brass running on brass!
