A system includes a seal assembly configured to retain a casing hanger within a wellhead. The seal assembly includes a main body; a lock ring coupled to the main body and configured to expand radially outward into a profile on an inner diameter of the wellhead; and an actuator, wherein the actuator is capable of transferring an axial force from the actuator into outward radial expansion of the lock ring until a tapered portion of the lock ring directly contacts a corresponding tapered portion of the profile, regardless of an initial distance from the lock ring to the profile prior to actuation of the lock ring.

Seal assembly with self-adjusting actuator

A wear bushing includes: a wear bushing body having one or more cavities formed therein; and one or more lug cartridges each disposed within a corresponding one of the cavities in the wear bushing body. Each lug cartridge includes: a biased lug configured to be transitioned between a first position in which the lug protrudes in a radially inward direction from an inner diameter of the wear bushing body and a second position in which the lug is retracted into the corresponding cavity of the wear bushing body; and a retainer configured to retain the biased lug in the second position.
