Sealing assembly for a gas turbine engine

A gas turbine engine comprising:

• a rotatable member extending axially along a center axis,
• a frame of the gas turbine engine surrounding the center axis and being non-rotatable relative to the center axis,
• a seal runner mounted to the rotatable member and operable to rotate with the rotatable member,
• a seal housing mounted to the frame and having a first annular surface extending at least partially along the center axis over the seal runner, and
• an annular body mounted to the rotatable member and having a second annular surface extending at least partially along the center axis, the second annular surface overlapping at least a portion of the first annular surface and being radially outward of the first annular surface.

A controlled gap radial oil sealing assembly in a gas turbine engine having a centre rotational axis defining an axial direction, the controlled gap radial sealing assembly comprising:

• a seal element located around a cooperating seal runner and sized to define a controlled sealing gap between them, the seal runner having an axial length extending beyond an axial width of the seal element into an oiled region of the engine;
• a first annular surface radially outwardly spaced from and extending substantially along the axial length of the seal runner, the first annular surface sealingly cooperating with a seal housing of the seal element;
• and
• a rotating second annular surface axially extending to overlap at least a portion of the first annular surface, the second annular surface radially outwardly spaced from the first annular surface relative to the center axis.
