Zusammenfassung:	An antifriction bearing (A) that enables a shaft (4) to rotate with minimum friction in a housing (2) includes a generally cylindrical outer race (46) located in an opening (12) in the housing, an inner race (48) located around the shaft, and rolling elements (50) arranged in rows between raceways on the outer and inner races. The outer race has a cylindrical exterior surface (56), whereas the opening in which the bearing is located has a flat wall (14, 16). A stabilizing block (C) may be attached to the outer race against its cylindrical surface, and this block lies along the flat surface of the housing opening to prevent the outer race from turning in the housing opening. A sensor module (B) is located within the environs of the bearing, and it contains a plurality of sensors (110, 112, 114) which produce signals that reflect conditions under which the bearing operates. Among the conditions monitored are speed, temperature and vibrations. Ce palier à roulement (A) permettant à un arbre (4) de tourner dans son logement (2) avec un minimum de frottement, comporte une bague extérieure de roulement (46), généralement de forme cylindrique, se trouvant dans une ouverture (12) ménagée dans le logement, une bague intérieure de roulement (48) placée autour de l'arbre ainsi que des éléments roulants (50) alignés en rangées entre des chemins de roulement sur les bagues, extérieure et intérieure. La surface externe (56) de la bague extérieure est de forme cylindrique et l'ouverture dans laquelle se trouve le palier comporte une paroi plane (14, 16). Il est possible de rattacher un bloc stabilisateur (C) à la surface cylindrique de la bague extérieure de roulement, ce bloc étant sous-jacent à la paroi plane de l'ouverture ménagée dans le logement, afin d'empêcher une rotation de ladite bague à l'intérieur de cette ouverture. Un module de détection (B), placé non loin du palier, comprend plusieurs capteurs (110, 112) générant des signaux rendant compte des conditions de fonctionnement du palier. Au nombre de ces conditions de fonctionnement faisant l'objet d'un contrôle figurent celles ayant trait à la vitesse, à la température ainsi qu'aux vibrations.
