    Quick question here. I have the two used rails shown in the picture along with the four bearing blocks. No use for them so I thought I'd offer the pair for sale, but I noticed that the linear bearings have significant movement axially on their own. What i mean is, if I grab a single block I can rock it quite noticably length-wise ont he rail. If however I put a pair together they become nice and firm, there's no radial play that I can detect by hand. Is this normal or does it indicate significant wear?
