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 components of 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, performed in order:
- a) securing the target holder to the first ring,
- b) turning the target holder in a circumferential direction to a specific angular position,
- c) mounting the magnetic target onto the target holder,
- d) magnetizing the magnetic material of the magnetic target after the step of mounting the magnetic target onto the target holder, and
- e) assembling the bearing by securing the first ring to the second ring.
A method for manufacturing a sensor ring for a sensor bearing unit, the sensor ring being configured for assembly with a fixed outer ring to form the sensor bearing unit, the method comprising:
- providing the sensor ring comprising a ring and an impulse ring, the impulse ring comprising a target holder and a magnetic target, the target holder being configured to be mounted on the ring and hold the magnetic target, the magnetic target being made of a magnetic material,
- wherein the method comprises the following steps:
- a) securing the target holder to the ring,
- b) turning the target holder in a circumferential direction to a specific angular position,
- c) mounting the magnetic target onto the target holder, and
- d) magnetizing the magnetic material of the magnetic target after the step of mounting the magnetic target onto the target holder.
A method for manufacturing a sensor bearing unit comprising:
- providing components of 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, performed in order:
- a) securing the target holder within a groove formed in a cylindrical surface of the first ring,
- b) magnetizing the magnetic material of the magnetic target after the step of securing the target holder to the first ring, and
- c) assembling the bearing by securing the first ring to the second ring.
