摘要

Production of a metal press-fitting element comprises precision casting an inner annular groove (10) of an annular ring (6) followed by metal cutting processing. Preferred Features: The metal cutting processing partly or completely includes the inner side of a cylindrical section (8). A low alloy carbon steel or a high alloy high grade steel is used for the precision casting.
