ANTIFRICTION BEARING FOR A SHAFT OR ROLLER AND METHOD FOR LUBRICATING SUCH AN ANTIFRICTION BEARING

摘要

The invention relates to an antifriction bearing for a shaft, cylinder or roller (2), especially for shafts, cylinders or rollers (2) of a rolling mill, in which metal strips are rolled, provided with a lubricant supply (9), which supplies a flowable lubricant to the antifriction bearing (3), and provided with at least one contactless labyrinth seal (13, 14) for sealing the antifriction bearing (3). The inventive antifriction bearing ensures a proper sealing of the bearing also when using contactless sealing labyrinth seals. To this end, the lubricant supply (9) supplies the lubricant according to the rotational speed of the shaft, cylinder or roller (2). The invention also relates to a method for lubricating an antifriction bearing, which is sealed by means of a labyrinth seal, using a lubricant stream and which prevents lubricant from escaping out of the seal.
