1. A rotating control device (RCD) system, comprising:
an RCD comprising:
a housing comprising a bore;
a seal element positioned within the housing;
a piston assembly supported within the housing and configured to drive the seal element to seal the bore; and
a bearing assembly supported within the housing and configured to enable the seal element to rotate relative to the housing, wherein the bearing assembly comprises a first bearing section positioned between the housing and the seal element and a second bearing section positioned between a piston of the piston assembly and the seal element,
wherein the piston assembly is configured to selectively actuate the seal element into at least a first configuration and a second configuration, the seal element in the first configuration extending into the bore and sealing with a tubular therein, and the seal element in the second configuration extending entirely through the bore and sealing the bore without a tubular extending therein; and
an annular blowout preventer having a non-rotating seal element configured to seal the bore,
wherein the housing is a one-piece housing, the annular blowout preventer being disposed within the one-piece housing and axially offset from the RCD.
