ABSTRACT:
A liner hanger has a housing with a pocket disposed on an inner wall surface and a slip slidingly engaged within the pocket. The liner hanger housing is secured in the string of casing. A setting mechanism connected to the slips is also located in the pocket. An actuator is mounted on the liner. As the liner is moved through the casing coupler, the actuator actuates the setting mechanism, causing the slips to move axially downward. As the setting mechanism moves downward, the slips move radially inward and grip the liner.
