Patent ID: 7347424

Claim:
A dynamic seal assembly, comprising: an outer annular case having an axially-extending cylindrical mounting portion with an outer end at least partially curled radially-inward and also having a radially-extending flange portion; an inner annular case nested in said outer annular case and having an axially-extending cylindrical portion with an end abutting said outer end to lock said cases together and a radially-extending flange portion with a distal end defining a mouth edge; an annular seal element disposed between said respective flanges portions of said inner and outer cases under a compressive load at a radially outward end and having a cantilevered lip extending radially inward from said radially outward end, said flange portion of said inner annular case extending more radially inward than said flange portion of said outer annular case such that said lip bends axially away from said inner annular case in operation; and a plurality of integral pull tabs circumferentially spaced from one another about said mouth edge and formed as one piece with said inner case of the same material, said plurality of tabs being closer to a point where said inner annular case abuts said outer end of said outer annular case than said annular seal element, and said plurality of tabs extending radially and axially away from said mouth edge to thereby define an unoccupied cavity for engagement by a seal removal tool to concurrently remove the entire assembly without changing the compressive load on said annular seal element.
