Abstract: A rotational device such as an industrial roll includes a rotational body such as a roll body and at least one journal member in the form of a stub shaft removably mounted and terminating within a journal opening provided in an end of the body. Engaged threaded portions provided in the journal opening and on the journal member prevent withdrawal of the journal member from the journal opening or separation of the abutting transverse stop surfaces on the journal member and in the journal opening. The journal opening includes a tapered portion and a tapered sleeve is interposed radially between the tapered portion of the journal opening and the journal member. A nut threaded onto the bearing member urges the tapered sleeve into engagement with the tapered portion of the journal opening further preventing relative rotational or transverse movement between the roll body and journal member. The abutting stop surfaces accurately position the bearing member axially with respect to the rotational body.
