shaft thicknesses virtually all the critical surfaces in the carrier roll 10 and on the journal 48 in particular are rotational surfaces this facilitates manufacturing to exacting tolerances and manufacturing the bearing members in particular in a single operation on a single machine the relatively minimal outer diameters and symmetry of the journal members 48 tend to minimize any residual imbalance such journal members could provide ancillary parts of the journal assembly such as the threaded nut 54 the lock washer 52 the substantially annular tapered sleeve 50 etc are all generally axially symmetrical therefore the imbalance in the carrier roll produced by these parts is negligible the roll 10 is easily taken apart and reassembled the journal assemblies are easily replaced with identical or different assemblies and with virtually no distortion of the bearing members and end heads thereby reducing the possibility of deleteriously affecting the balance of the individual components according to the preferred embodiment of the invention the assembling of the journal assembly 18 to the roll body 12 occurs in the following manner the roll body 12 and individual journal member s 18 are manufactured neither is balanced during or after manufacturing or during assembly one.
