Abstract
Plain bearing elements comprise at least one single-layer metallic bearing material (4) having a sliding surface (6) with lubricating oil pockets (10). The depth (T) of the open oil pockets (10) is 0.03 mm to 0.3 mm, and the ratio of the pocket area to the pocket depth is 10 to 40 mm. The plain bearing elements exhibit superior running qualities and properties. The depth of the oil pockets (10) may be adapted to the service viscosity of the lubricating oil. The oil pockets (10) in the same plain bearing element may also have varying depths (T) and be provided only in predetermined regions of the plain bearing element.
