A deep groove ball bearing having an inner ring, an outer ring and a plurality of rolling elements set between the inner and outer rings. The rolling elements have a diameter D.sub.w ≤ 0.5H.sub.1 , up to D.sub.w ≤ 0.35H.sub.1 . H.sub.1 is the radial dimension of the bearing in the sense of thickness and is numerically equal to half of the difference between the outer diameter and inner diameter of the bearing. By using sufficient number but smaller size of rolling elements, the deep groove ball bearing can obtain enhanced axial and radial rigidity, which is not only conducive to reducing creep and wear of bearing mating surfaces, avoiding early failure of bearings, but also improving the rotational accuracy of equipment, avoiding vibration, noise and other problems caused by insufficient bearing rigidity, fully meeting the comprehensive needs of rotating equipment for bearing performance.
