Device for guiding movement, sliding element, and item of furniture

A device having an arrangement of bars, on which the device can be fitted, wherein the device is provided for guiding movement of a sliding element, which can be arranged between opposite side walls of an item of furniture, wherein the device comprises a carrier rail, which can be fitted on the arrangement of bars on the side wall of the item of furniture, and a pull-out rail, which can be displaced relative to the carrier rail, so that, in the fitted, use state of the device, the sliding element can be supported on a bearing surface of a rail body, extending in the longitudinal direction of the device and belonging to the pull-out rail, and can be moved linearly relative to the arrangement of bars, wherein the pull-out rail is mounted for displacement along a bearing portion of the device by way of rolling-body bearing mechanisms of the device, wherein a rail upper side of the rail body of the pull-out rail comprises an outer side and an inner side, which is located opposite the outer side, wherein the inner side can be brought into abutment against the rolling-body bearing mechanisms, wherein, as seen in respect of the use state of the device, the bearing surface for the sliding element is offset vertically upward in relation to the outer side of the rail upper side of the rail body of the pull-out rail, wherein the bearing surface for supporting the sliding element is present on a crosspiece portion, which is formed in one piece with the rail body of the pull-out rail, wherein the arrangement of bars comprises a vertical bar portion and a horizontal bar portion, wherein holding mechanisms for releasably anchoring the device on the arrangement of bars are present, wherein the crosspiece portion is specifically configured such that, in the use state of the device, the bearing surface is spaced apart vertically upward to some extent in relation to an upper side of the nearest horizontal bar portion of the arrangement of bars, wherein the distance between the bearing surface and the upper side of the horizontal bar portion of the arrangement of bars is between 1 and 5 millimeters, and

• wherein the crosspiece portion is formed over the length of the rail body,
• wherein the rolling-body bearing mechanisms comprise roller-form bearing bodies and spherical bearing bodies held within a common bearing cage, and
• wherein the rail body and the crosspiece portion are in the form of a single piece bent sheet metal part.
