Patent ID: 7396021

Claim:
In a roll assembly where a roll stub rotates about an axis relative to a stationary support, a seal assembly comprising: a rotatable support fixed to the roll stub; an annular and radially directed seal surface fixed on one of the supports; a seal ring on the other of the supports having a lip engageable radially with the seal surface; means including at least one radially compressible support element that is substantially less stiff than the seal ring between the other support and the seal ring for biasing the lip radially against the seal surface while permitting radial shifting of the seal ring relative to the other support; an abutment fixed on the other support; and means including a clamp body rotationally fixed to the other support, directly axially engaging the seal ring, and pressing the seal ring axially directly against the abutment and axially interengaging tooth formations on the clamp body and on the seal ring for arresting the seal ring on the other support against angular movement thereon while permitting relative radial movement.
