Abstract

A unitized seal includes a first seal casing having a plastically deformable radially-extending unitizing flange and a second seal casing having at least one axially extending projection. The projection has an engagement surface which confronts the unitizing flange for engagement therewith. Upon installation of the seal, the projection axially deforms the unitizing flange in a localized area about the projection. Upon initial rotation of the seal the projection further axially deforms the remainder of the unitizing flange within one rotation. This arrangement minimizes the production of metal chips and/or abraded elastomeric particles during seal break-in and further minimizes resistance to seal rotation during break-in.
