ABSTRACT A liner hanger is shown of the type used to hang a well liner in a surrounding well bore. The hanger includes a tubular mandrel which is connectible in a liner string. A set of circumferentially-spaced gripping slips are mounted about the mandrel with each slip having a spring arm extending therefrom in alignment with the axis of the mandrel, A tapered, slip expander cone is mounted on the mandrel exterior above each of the slips for expanding the slips radially outwardly in the direction of the surrounding well bore responsive to opposite relative movement of the slips and cones. At least one channel guide is formed on the exterior of the mandrel in longitudinal alignment with one of the expander cones. The channel guide includes a slot portion for slidably receiving the spring arm of one of the gripping slips for supporting the slip on the exterior of the mandrel. A setting mechanism urges the slips in the direction of the cones to effect the outward, radial expansion of the slips to thereby hang the mandrel, and, in turn, the liner within the well bore.
