| 摘要 |
The present invention relates to a rollbearing of the type comprising an external cage (100), an internal cage (120) and rollbearing bodies (150) distributed between the external cage (100) and the internal cage (120), one of these cages being provided in order to be fixed onto a framework (500), characterised in that it comprises a multiple-pole annular magnet (200) on the mobile cage, two metallic half-shells (300, 350), fitting into each other, receiving a winding (400) and placed on either side of the magnet (200), first fingers (333) connected to the shells and designed to interact with the ribs (510) provided on the framework (500) in order to limit the relative rotation between the corresponding shell and the framework (500), and second fingers (334) placed between the stationary cage and the framework (500) in order to stop axial displacement of the corresponding shell. <IMAGE>
