I bought a 1" diameter axle for a Harley rear wheel. The axle was new and didn't cost very much. It came as a raw steel unit so that I could chrome it after I made sure it fit. Well guess what, the axle didn't fit, wasn't concentric and was .023 larger ( 1.023" ) than the listed true inch. I measured the run out and turned it down on my lathe, giving it a .002 slip fit( .998 ). Now it fits the bearing just right and I still have room for the chroming process. So when you buy something from a reputable dealer, check it first before you install it.
