Roll that includes a roll axle, a roll jacket, and a bearing ring positioned to rotatably support the roll jacket, and calender that includes the roll. The bearing ring is non-rotatable but is radially movable relative to the roll axle. A locking device is positionably adjustable to selectively block and unblock a radial lift movement, and the locking device includes a rotatable part having a longitudinal opening. The rotatable part is rotatable into a first rotational position in which the longitudinal opening is oriented substantially parallel to a direction of the radial lift movement, and is rotatable into a second rotational position in which the radial lift movement is blocked. The calender further includes a neighboring roll arranged to form a nip with the roll, and at least one further roll. The neighboring roll and the further rolls are mounted for displacement in the pressing direction, and a device arranged to selectively block and unblock the displacement of the neighboring roll.
