<p>Double-row angular ball bearing comprises an outer (1) and an inner ring supporting on their shoulders (1.1, 1.2) bearing balls (3.1) held in a cage (3.2, 4.2). The diameter of the ball bearing tracks is different. Both cages are window cages made of plastic with pockets for the bearing balls. One of the cages is provided on its axially inward-facing end with several spacers (4.5) uniformly arranged along the periphery and several holding lugs (4.4) uniformly arranged along the periphery, which engage in a corresponding groove (1.3) in the inner or outer ring. The spacers of one cage prevent axial displacement of the other cage. Preferred Features: The bearing balls have the same or different diameters. The pockets of the cages are provided with holding elements (3.3, 4.3).</p> |
