A single-row or double-row rolling bearing comprises a rimless inner race 8, a rimless outer race 7 and rollers 9. In order to ensure a high radial and axial load capacity of the bearing, to facilitate mass-production of the rollers and to reduce friction resulting from a sliding instead of the desired rolling motion of the rollers, at least the regions adjacent the two end faces 6 of each roller are curved along their longitudinal extent. Alternatively, each roller may be curved convexly with the same radius along its entire length. Whatever roller is used, the, or each, centre 11 of the, or each, curvature is disposed on the opposite side of the bearing axis 10 and the smallest radius 12 of the, or each, curvature is greater than ten times the length of the roller. The shape of the tracks of the inner and outer races is substantially the same as that of the rollers. <IMAGE> |
