Abstract: A radial shaft seal for dynamic applications is disclosed. The shaft seal has a case member and a resilient sealing body attached to the case member. The sealing body includes an annular elastomeric member and a resinous ring. The elastomeric member has a radially extending section and a distal end. The resinous ring has a radially extending portion and an edge. The radially extending section is contiguous to the radially extending portion to form a composite seal lip body. The composite seal lip body, as installed, is positioned so that the distal end of the radially extending section and the edge of said radially extending portion engage the shaft in fluid tight relation by the elastomeric member and by the reaction forces of the resinous ring. Therefore, a portion of the reaction forces is shared by the edge and the distal end so as to reduce the wear in the distal end.
