Review on Donepart 99502H 2RS Bearings Double Rubber by Jacob Leon

The inner diameter is specified as 5/8", which corresponds to 0.625". It measures .621" which makes it too small to fit on a 5/8" axle shaft. The outside diameter measures 1.3746 on a calibrated micrometer. Width measures 0.436 inches. All 4 do not turn evenly or smoothly, roughness can be felt and heard from the egg.
