Abstract: A floating bearing has a rotating, rotationally symmetric machine part (6), with an outer ring (10), which is non-rotatably supported in an intermediate bearing (1) that is located in the installation space of a housing (3, 8). An inner ring (11) is non-rotatably connected with the rotating machine part (6). A locking mechanism inhibits a relative motion in the circumferential direction between the housing (3, 8) and intermediate bearing (1) and permits a relative motion between the housing (3, 8) and intermediate bearing (1) along the rotation axis of the machine part (6).

Abstract: A direct drive for a printing press with lateral register adjustment includes a rotor and a stator, and a connection for mechanically connecting the drive with a stationary support bearing, wherein the rotor is connectable with shaft of a printing press cylinder with the connection being a torsionally stiff spacer installed directly or indirectly on the outer jacket of drive, which is designed to be elastic in the direction of the motor axis to compensate axial motions of the attachable printing press cylinder shaft.

Abstract: The invention relates to a bearing of a drive shaft (6) by means of an intermediate bearing (1) and a roller bearing (5, 10, 11) in relation to a housing (3, 7, 8), characterized in that it comprises a locking element (4) which blocks a relative movement in the rotation direction between the housing (3, 7, 8) and the intermediate bearing (1) and allows a relative movement between the housing (3, 7, 8) and the intermediate bearing (1) along the rotational axis of the shaft (6). According to the invention, the material of the locking element has a high resistance to corrosion and consists essentially of brass or stainless steel and the housing (3) comprises a plain bearing bush made of plastics (14).
