Abstract
The invention concerns an instrumented antifriction bearing device, provided with a non-rotating part including a non-rotating ring and sensor element, a rotating part including a rotating ring and encoder, and at least a row of rolling bodies arranged between two raceways of the non-rotating and the rotating rings. The non-rotating sensing element and the rotating encoder form an assembly detecting rotation parameters. The device includes a maintenance device for temporarily maintaining the angular indexing of the encoder relative to the sensing element in an angular position, wherein the encoder generates in the sensing element a reference signal. The maintenance device temporarily maintains the angular indexing device in position until released, as for example, by the axial displacement of at least part of an element of the device towards the row of rolling bodies.
