ABSTRACT:
A unitized oil seal is provided with axially extending and radially protruding elastomeric ribs for preventing rotation of one of the oil seal members about a shaft or within a bore. The ribs are designed to reduce installation forces and thereby reduce seal damage due to excessive deformation during installation.
