A barrel nut with features for reducing tensile stresses under heavy load within the barrel nut has a partial-cylindrical body having a first planar end surface and a second planar end surface. A threaded bore extends through the partial-cylindrical body with a central axis substantially parallel to the first planar end surface and the second planar end surface. At least one groove is formed in each of the first planar end surface and the second planar end surface, the groove having a rounded surface extending at least a part of a distance between a curved upper surface of the partial-cylindrical body to a bottom surface thereof in a direction substantially parallel to the central axis of the threaded bore.

A method and apparatus for suspending a load is provided. A load is connected to a yoke by one or more mounting links. The mounting links are connected to the yoke by a yoke pins and to the load by load mounting pins. The mounting links are connected to the pins by spherical bearings that enable the mounting links to move relative to yoke and to the load to accommodate movement of the load, such as movement caused by thermal expansion of the load. A stop collar is arranged around the load mounting pins to limit free movement of the mounting links about a longitudinal axis so that the mounting links cannot contact the load.
