The invention relates to a planetary roller bearing (9), comprising an outer ring (10), an inner ring (11), and rolling bodies (12) accommodated therebetween that have grooves (13), which are in engagement with grooves (14, 15) formed on the outer ring (10) and the inner ring (11). In the region of the axial ends of the rolling bodies, the rolling bodies (12) are each provided with cylindrical surface (16, 17). Between the cylindrical surface (16, 17) and the inner ring (11), and between the cylindrical surface (16, 17) and the outer ring (10), a gap (18, 19) is formed in each case, the radial width of which is dimensioned such that a tilting of a rolling body (12) due to a contact between the cylindrical surface (16, 17) forming a support surface and the inner ring (11) or the outer ring (10) is limited. |
