Due to their versatility and comprehensive performance, single-row deep groove ball bearings are the most widely used bearings in the world. Characterized by low friction, high rigidity, and smooth, quiet operation, they are suitable for high-speed applications and capable of simultaneously supporting radial and axial loads. Because the contact area between the steel balls and the raceways is relatively small, these bearings have a lower load-carrying capacity compared to other types of rolling bearings of the same size; however, they can accommodate a certain degree of angular misalignment between the inner and outer rings.
