ABSTRACT:
A seal for fluid tight sealing between a shaft and a member having an opening through which the shaft extends. The member includes a sealing surface perpendicularly disposed to the shaft axis and the seal is of a homogeneous "right angle" construction having hub and flange portions. An inwardly extending continuous lip establishes a seal between the hub and shaft, while an annular ridge defined on the flange engaging the member sealing surface sealingly engages the surface whereby a sealed relationship exists between the shaft and member regardless of the presence of eccentricity therebetween during shaft rotation or linear displacement. Seal positioning means maintain the flanged ridge in engagement with the member sealing surface and annular spring means are employed upon the hub to bias the lip into engagement with the shaft.
