  • Patent number: 8007183
    Abstract: The invention relates to a double-row angular contact anti-friction bearing having a split outer bearing ring, a one-piece inner bearing ring, and anti-friction bodies located in two rows between the two rings. The outer bearing ring is split axially into two individual rings. To permit simple, reliable and secure transport of the bearing, the individual outer bearing rings are interconnected by a connecting element in a positive fit that allows play and the outer surfaces of the individual rings have at least one recess, which is spanned by the connecting element. At least the recess of an individual ring has a groove, in which a hook element on the connecting element engages in a positive fit and the individual rings can be twisted in relation to one another.
