Abstract

A rotating control device (RCD) for a drilling system includes a seal assembly with a seal assembly housing, a seal element positioned within the seal assembly housing, and a piston positioned within the seal assembly housing. The piston is configured to drive the seal element axially within the seal assembly housing to enable the seal element to form an annular seal about a tubular as the tubular rotates, moves axially, or both.
