Abstract: A bearing isolator seal having a shut off O-ring is tolerant of axial rotor-stator misalignment and provides an enhanced static seal while minimizing rotational wear. A tapered section of the stator is overlapped by the shut off O-ring. When the rotor is static there is no axial misalignment, and the shut off O-ring is pressed against the tapered section, forming an enhanced seal. During rotor rotation, increased axial misalignment moves the O-ring away from the tapered section, reducing rotational wear. The stator can extend horizontally beyond the tapered section and below the O-ring, so that if the rotor moves beyond a maximum misalignment, there is a “line on line” fit between the stator and rotor. The bearing isolator seal can include labyrinth technology, and the tapered section can include a contour that allows the shutoff O-ring to drag along the surface of the tapered section with no hang-ups or binding.
