The invention relates to a rolling bearing (1) having a first bearing ring (2), a second bearing ring (3) and a plurality of rolling bodies (5) which are arranged between the first bearing ring (2) and the second bearing ring (3). Here, the rolling bodies (5) are arranged in at least four rows (11, 12, 13, 14), at least two rows (11, 14) have a first reference diameter (Tk1, Tk4), at least two further rows (12, 13) have a second reference diameter (Tk2, Tk3) which is different from the first reference diameter (Tk1, Tk4), and those rows which have in each case the same reference diameter are arranged symmetrically with respect to a predefined plane (ME) which is aligned perpendicular to a longitudinal direction (LR) of the bearing.

L'invention concerne un palier de roulement (1) qui présente une première bague de palier (2), une deuxième bague de palier (3) et plusieurs corps de roulement (5) disposés entre la première bague de palier (2) et la deuxième bague de palier (3). Les corps de roulement (5) sont disposés en au moins quatre rangées (11, 12, 13, 14) dont au moins deux rangées (11, 14) présentent un premier diamètre de cercle partiel (Tk1, Tk4) et au moins deux rangées (12, 13) présentent un deuxième diamètre de cercle partiel (Tk2, Tk3) différent du premier diamètre de cercle partiel (Tk1, Tk4). Les rangées qui présentent le même diamètre de cercle partiel sont disposées symétriquement par rapport à un plan (ME) prédéfini perpendiculaire à la direction longitudinale (LR) du palier.
