Disclosed is a double-row bearing assembly improved to have enhanced durability. The double-row bearing assembly according to the present invention comprises an inner race and an outer race for straining a plurality of rolling elements arranged in a double row of first and second parallel rows to allow a rolling motion. The outer race has a dust collecting unit prepared in between a rolling element group of the first row and a rolling element group of the second row to accommodate particles generated by the rolling motion of the rolling elements. By the same, the scattering of minute particles generated during the driving of a bearing can be prevented and noise and vibration sources can be minimized, thus increasing the functionality and reliability of the bearing. |
