Keyless Bushings Engineering Information SURFACE FINISH Recommended surface finish for shafts and hub bores to be used with Fenner Drives Keyless Bushings is between 32 and 125 micro-inch RMS. A smoother finish such as that found on components supplied TG&P (turned, ground and polished) ח is NOT recommended and can result in a failure of the connection. Note that surface finishes below 32 micro-inch RMS can be roughened using longitudinal abrasion with a bastard file, emery paper or similar to achieve a surface finish within the recommended range.
