• a) A support bolt connectable to the extension arm, the support bolt having a first thread;
• b) a rotatable by a tool bearing member having a second thread which engages in the first thread;
• c) a bearing bush in which the bearing element is at least partially received;
• d) an axially rotating in a height, projecting radially to the longitudinal axis of the bearing element collar which is supported directly or indirectly on the bearing bush in a first axial direction of the bearing element;

wherein the collar is supported against the first axial direction on a sleeve of the bearing unit, which is inserted into the bearing bush.

The sleeve of the bearing unit allows easy mounting of the bearing unit. The sleeve can be used before assembly of the bearing element in the bearing bush. To secure the bearing element no pin or the like must be subsequently inserted into the bearing bush. At the same time, the sleeve takes up little space and thereby enables a very compact design of the bearing unit. The sleeve holds the collar of the bearing element axially substantially immovably on the bearing bush. Preferably, the sleeve holds the collar with a clearance fit on the bearing bush. When lifting and lowering the wing, it can no longer come to a large axial movement of the bearing element and thus to a tilting of the bearing element.

The first axial direction preferably runs counter to the loading direction of the bearing unit, i. H. against the direction in which presses the weight of a wing in the operating condition of the bearing unit on the bearing unit.

The first thread of the support bolt is preferably in the form of an internal thread, the second thread of the bearing element is preferably formed in the form of an external thread.

More preferably, the bearing element is designed in the form of a screw, wherein the collar is formed annularly on the screw head.

After mounting the bearing unit sleeve and collar are preferably not nondestructive separable.

The sleeve may have in the first axial direction a distance projection extending away from at least one projection, the axial length of which corresponds substantially to the axial length of the collar. As a result, a defined seat of the collar is achieved relative to the projection or the projections.

The distance projection can be formed in one piece or in several parts. Preferably, the distance projection is formed radially circumferentially to the longitudinal axis of the sleeve.

In a further embodiment of the invention, the collar is supported in the first axial direction via a thrust bearing of the bearing unit on the bearing bush. The thrust bearing allows a particularly low-friction rotation of the bearing element relative to the bearing bush.

In a particularly preferred embodiment of the invention, the support pin is supported via a first radial bearing of the bearing unit directly or indirectly, in particular directly, on the bearing bush. The first radial bearing is preferably designed in the form of a needle bearing.

A particularly stable design of the bearing unit is achieved if the support bolt continues to be indirectly or directly, in particular directly, supported by a second radial bearing on the bearing bush. The second radial bearing is preferably designed in the form of a needle bearing.

The / the radial bearing and / or the thrust bearing are preferably pressed in the bearing bush.

The support bolt may have a spacer collar, which serves in the first axial direction as Verstellanschlag against the first radial bearing and against the first axial direction as Verstellanschlag against the second radial bearing.

The sleeve preferably extends in the first axial direction between the first radial bearing and the axial bearing.

More preferably, the bearing unit between the first thread and the second thread on a rotation lock to prevent an adjustment of the bearing unit during opening and closing movements of the wing. The first thread and / or the second thread can have a recess in which an anti-rotation element is arranged, which has a lower hardness than the bearing element and / or the support element.

Preferably, the anti-rotation element in the form of a string, in particular a Perlonschnur formed.

The object of the invention is further achieved by a fitting arrangement for connecting a sash to a fixed frame of a window, a door or the like, wherein the fitting arrangement comprises a stay, a fastener and a bearing unit described above.

The fastening element is preferably designed in the form of a housing in which the bearing unit is accommodated.

The object of the invention is finally achieved by a window, a door or the like with a sliding wing and a previously described fitting arrangement.
