Abstract
A machine can include a radially inner component, a radially outer component, and a circumferential seal assembly between the inner and outer components. At least one (e.g., both) of the inner and outer components can be a rotor. The circumferential seal assembly can include a circumferential metallic mount, a circumferential ceramic runner, a circumferential carbon seal, and one or more spring energized seals. The spring energized seals can prevent rotational slippage between the metallic mount and the ceramic runner. The spring energized seals can be necessary to prevent rotational slippage between the metallic mount and the ceramic runner for at least one standard operating state of the machine.
