Abstract
A sintered friction bearing for motors and gears with a bearing surface, which is formed by a bearing bore and can have a lubricant from lubricant depositories in the bearing. The bearing bore has alternating highly compressed, small-pored bearing surfaces distributed over the circumference and slightly compressed, open-pored lubricant depositories from one front face to the other front face of the bearing. Lubrication of the sintered friction bearing is improved because the lubricant depositories are embodied as grooved structures with at least two longitudinal grooves, which are inclined at an acute angle with respect to a center axis of the bearing bore from one front face to another front face of the bearing.
