摘要

The bearing has a positive guide including a gear wheel (7) connected with a cage (5), and engagement units formed as perforated plates (11). Guide rails (1) are movably supported against each other over balls (3) and are provided with axially extended recesses (9). The engagement units are axially extended along a movement direction of the rails. The recesses are connected to a front surface of one of the rails, and extend parallel to side surfaces of the rails, where the front surface lies against another rail. The engagement units are retained in the recesses.
