  • Method for manufacturing an integral duplex bearing
    Patent number: 8973271
    Abstract: In certain embodiments, a method for manufacturing an integral duplex bearing having an outer ring, a first inner ring, and a second inner ring includes forming a first outer raceway and a second outer raceway in an inner surface of the outer ring. The method further includes forming a first inner raceway in an outer surface of the first inner ring and a second inner raceway in an outer surface of the second inner ring while the first inner ring and the second inner ring are joined together. The first and second inner rings each have an outer surface diameter less than an inner surface diameter of the outer ring such that the first and second inner rings may be positioned inside the outer ring with the first inner raceway located adjacent to the first outer raceway and the second inner raceway located adjacent to the second outer raceway. The method further includes separating the first inner ring from the second inner ring.
