This invention relates to a single-row radial rolling bearing used advantageously for high-speed spindles. A single-row radial rolling bearing has an inner race (1) or an outer race (2) shaped as a spherical surface sector of radius rb=r/cos alpha o, beginning at an axis (3) of a bearing, the operating angle of which is alpha o=3 DEG to 45 DEG , and at those races there is situated a protecting element (4). |
