Abstract
Preloaded connection for supporting an annular body from an annular suspension joint. The connection includes an actuating ring, a split locking ring and a retaining nut which are positioned between the annular body and suspension joint. The connection is preloaded by applying an axial force to the actuating ring causing the locking ring to be expanded outwardly with the annular body becoming preloaded in compression and the suspension joint preloaded in tension with the preload force passing through the mating surfaces.
