Seal to prevent lubricant escaping, and rolling stand having said seal

A rolling stand (200), comprising:

• at least one roller (210) with two roll journals (212) and a roller body (214) for rolling a rolled material;
• at least one chock (220), optionally with a bearing bush (222), for rotatably supporting the roller (210) in the rolling stand (200),
• wherein the chock (220) or the bearing bush (222) forms a receiving opening for receiving one of the roll journals (212), optionally with a drawn-on journal bush (216),
• wherein an inner diameter of the receiving opening is larger than an outer diameter of the roll journal, optionally with the drawn-on journal bush, in such a manner that, between the chock or the bearing bush and the roll journal or journal bush, an annular gap (300) for receiving a lubricant (320) is formed;
• and
• a seal for sealing the annular gap, which represents a lubricant space, at least in a predetermined circumferential angular range, arranged in a non-rotatable manner relative to the rotatable roller at an end proximal to the roller body and/or at an end remote from the roller body of the chock (220) or the bearing bush (222);
• wherein the seal (100) is at least partially formed from an elastic material,
• wherein the seal has at least two cavities (110) which are separated from each other in a circumferential direction and which are open towards the lubricant space of the bearing for feeding the lubricant (320) from the lubricant space (300) of the bearing to be sealed into the cavities,
• wherein a groove (230) that is open towards the roll journal (212) and into which the seal (100) can be inserted is formed at the end proximal to the roller body and/or at the end remote from the roller body of the chock (220) or the bearing bush (222), and
• wherein in an unloaded state, an axial width a of the seal (100) is greater than a width A of the groove (230) in the axial direction (R).
