I was concerned about what I was getting after reading some of the other reviews. Not sure what they got but mine was all 1,000 inches. Unfortunately the hot rolled bar I had was 1.005 inches so it didn't fit. It was my fault, not the bearings. Probably a cold rolled bar would be fine. I just bent the rod to the diameter I wanted and they worked fine.
