Let's suppose I want to allow a shaft to rotate and slide with minimal clearance. The shaft won't rotate quickly, maybe 1 RPM maximum, but I can't tolerate much, if any, radial clearance. Let's also say, for fun, that I want to stick with plain bearings. I can think of two solutions -- one in which I ream and lap the inside of a bronze bushing until I get the right clearance and just leave it. We say it'll wear slowly and the clearance is lapped in and there's no issue.
I prefer to make things adjustable, however. Is there any chance I could get away with using a split bushing? I usually only see split housings used for clamping and not as bearings, but can this be done and is it a good idea? What's the closest thing to "rotary gibs"
