Abstract
A method for centering an impulse ring of a bearing unit on the center of rotation of the bearing unit including a first ring and a second ring. The impulse ring provided with a target having pairs of magnetic poles, and with a fixing sleeve. The method provides a) inserting the impulse ring between the first ring and the fixing sleeve, the first ring and the fixing sleeve being configured to maintain the impulse ring in an axial direction of the bearing; b) recording an angular signal over one mechanical turn of the impulse ring, the angular signal being generated by detection configured to cooperate with the pairs of magnetic poles; c) determining a total pitch deviation vector of the impulse ring based on the angular signal; d) shifting the impulse ring in a radial direction of the bearing, and e) securing the impulse ring relative to the first ring.
