Abstract
The invention relates to a device and a method for mounting a bearingon a roll neck and for removing the bearing from the roll neck of a roll. Known devices of this type have a first and a second piston/cylinder unit. They also have a stop ring, fixed in the axial direction A at the end of the roll neckremote from the body, which acts as a stop for the inner pistonof the first piston/cylinder unit. In addition, the known devices have a nutwhich can be screwed onto an external thread of the inner piston to secure the bearingin the axial direction, in particular during a rolling operation. As an alternative to the known prior art, the present invention provides that an annular cylinderserves both as a cylinder for the first piston/cylinder unit and as a cylinder for the second piston/cylinder unit. For its function as a cylinder for the second piston/cylinder unit, said annular cylinder is covered to a certain ex ent on its side remote from the body by an annular cylinder cover. The cylinder coverserves, together with an outer flangeof an outer piston, to axially delimit a removal pressure chamberof the second piston/cylinder unit.
