Abstract: A pillow block bearing seal for sealing the shaft opening around the shaft of a pillow block, having a stator assembly, a rotor, and a resilient cylinder sleeve. The stator assembly has a cylindrical base having an axial length that is configured to accept the shaft passing there through, and a stator extending annularly from an axial end of the cylindrical base. The rotor is configured to attach to and rotate with a rotatable shaft, and has an axially inward-facing surface that confronts the axially outward-facing surface of the stator to define labyrinth interface passage. The resilient cylindrical sleeve is fixed to an outer surface of the cylindrical base for contact with a pair of annular ribs of the bearing housing, for stabilizing the alignment of the center line of the shaft with the bearing housing.

Abstract: A labyrinth seal including a stator and a non-contacting rotor, and annular elastomeric seals. The confronting surfaces of the stator and rotor define at least one interface passage, including a radially-outermost annular interface passage between an annular, outermost, radially-extending projection of the stator and an annular rearwardly-extending distal projection of the rotor that overlaps the radially-extending projection of the stator, the radially-outermost annular interface passage tapering outwardly and rearwardly at an acute angle relative to an axial reference line. The annular elastomeric seals are stationary with the stator during dynamic operation of the rotor, and are not contacted by a surface of the rotor during dynamic operation. The interface can also have two radially-disposed exclusion chambers, the outer exclusion chamber being defined in part by a radially-inboard projection of the rotor. The stator can have a projection providing a contact avoidance interface position inboard of at least two contaminant-excluding interfaces.
