摘要：
A nut (1, 13, 21, 25) for a planetary roller screw drive is provided. A sleeve (14) which is produced by metal forming is provided, and two rings (16) that lie at a fixed distance with respect to each other in the axial direction are provided in this sleeve. In order to engage planets (3), the one ring (16) has the one groove profile (18), and the other ring (16) has the other groove profile (18).
