  • Patent number: 5285950
    Abstract: A low-cost sprag retainer is disclosed which is particularly useful in high volume applications. The retainer is formed of two generally linear wire portions which are spaced by a first distance. Cross members are placed across the linear members, spanning the first distance and then secured to the linear members. The linear members are then rolled upon themselves such that their ends meet in abutting contact to form rings. The ends are then welded together. The method of the present invention reduces production complexity for sprag retainers in high volume applications.
