Abstract

A rotational seal assembly is associated with a rotating component. The rotational seal includes an outer casing, an inner casing, a rotational seal connected to the outer casing and the inner casing, and a followability enhancer. A section of the rotational seal includes a heel portion and a toe portion. The rotational seal is configured to contact, via a first surface of the section of the rotational seal and during operation of the rotating component, the rotating component. The followability enhancer is configured to contact, during the operation of the rotating component, a first region of a second surface of the section of the rotational seal that is associated with the toe portion. The followability enhancer is configured to not contact, during the operation of the rotating component, a second region of the second surface of the section of the rotational seal that is associated with the heel portion.
