Abstract
Shaft seal consisting of an annular body of elastic material, comprising a fastening flange (1;12), a substantially axially extending flexible hinge portion (6;13) and a sealing lip (7;14). The fastening flange, hinge portion and sealing ring (5) form a single piece, and the sealing ring (7;14) has a cylindrical contact surface with the shaft extending over substantially the entire length of the sealing ring. This length is sufficient to receive one or more tensioning elements (10,11; 15,16) of an operative width to guide the sealing ring concentrically on the shaft over its entire axial length.
