Abstract
A high-axial load bearing assembly is provided for use with a radially expandable tool such as an expandable liner hanger. Exemplary embodiments of axial load bearing assemblies operate independently of external casing pressure and internal tubing pressure. The assemblies do not rely on movable slips or the physical characteristics of the sealing members to grip the casing and bear the axial load. The gripping and sealing functions are largely separated between gripping and sealing sub-assemblies. Hardened metal features which undergo radial expansion during deployment are provided with expansion stress-relief features.
