An axial preloading device can include a shell having an inner surface that defines a radially interior channel, the inner channel defining an axial direction, one or more moveable housing members disposed at least partially within the interior channel and configured to move relative to the shell in the axial direction, and a wedge assembly connected to the shell and disposed in contact with the one or more housing members. The wedge assembly can be configured to be moved radially relative to the shell and the one or more housing members to push the one or more housing members axially. The wedge assembly and the one or more housing members define a shaft opening when installed on the shell.
