Abstract

The invention relates to a bearing bush (10), in particular a plain bearing bush, for the rotatable mounting of a shaft (34) or a roller (52). The bearing bush (10) has at least one radial opening (16), through which lubricant from the surroundings of the bearing bush (10) can be fed into the interior of the bearing bush (10). At least one elongated recess (16) is formed in the inner shell of the bearing bush (10). The recess (16) is formed as an opening passing completely through the bearing bush (10) over the entire longitudinal extent (a) and width (b) thereof. The bearing bush (10) is produced from a flat plate-like body (12), into which the opening (16) is introduced by a punching tool and which is subsequently rolled in order to form the cylindrical bearing bush (10).
