Inner surface of bearing shell, comprising specifically shaped polishing pattern created with computer controlled device

摘要

When the inner surface (12) of a bearing shell is polished a minute texture (13) is created by the brushes, resulting in areas influencing the performance of the bearing. When the brushes are guided across the surface (12) along particularly shaped lines (13) the wear and tear of the surface (12) is imitated in advance, avoiding a period of an inadequate performance. The polishing lines (13) are guided along both sides of the lubricant inlet (14) forming intersections with acute angles in the center of the bearing surface (12).
