Abstract
A double row angular contact ball bearing having a one-piece inner ring and a one-piece outer ring and containing therebetween a first row of a larger number of balls inserted in a maximum-type manner and a second row of a lesser number of balls inserted in a manner similar to the Conrad-type manner. The balls of each of the first and second rows are held by two separate cages. The raceway of the outer ring for the second row of balls is an angular contact raceway laterally open at one side, whereas the other raceway of the outer ring for the first row of balls is cut out from the bottom thereof in a substantially radially outward direction and then laterally toward an end face of the outer ring to form an inner cylinder bore surface. By such an arrangement, it is possible to insert a greater number of balls into the second row of balls than was the case in the prior art bearing of this type, resulting in increased load capacity, longer life, and improved reliability.
