Abstract
The method provides for the manufacturing a sensor bearing unit including a bearing having a first ring and a second ring capable of rotating concentrically relative to one another, and an impulse ring provided with a target holder secured to the first ring and with a magnetic target mounted on the target holder. The method further includes securing the target holder to the first ring and magnetizing the magnetic material of the magnetic target after the step of securing the target holder to the first ring.

A method for manufacturing a sensor bearing unit comprising:
- providing a bearing comprising a first ring and a second ring capable of rotating concentrically relative to one another, and an impulse ring comprising a target holder for mounting on the first ring and a magnetic target made of a magnetic material,
- wherein the method comprises the following steps:
- a) assembling the bearing such that a row of rolling elements lies between the first ring and the second ring,
- b) after step a), machining the first ring by turning the bearing to form a groove on the first ring,
- c) securing the target holder inside the groove of the first ring,
- d) turning the target holder in a circumferential direction to a specific angular position,
- e) mounting the magnetic target onto the target holder, and
- f) magnetizing the magnetic material of the magnetic target after the step of mounting the magnetic target onto the target holder.
