Advanced Elastomeric Seal Design and Material for Automotive Crankshaft Applications 870507
The small, lightweight engines of today require elastomeric lip seals to operate at higher shaft speeds and elevated temperatures while retained in aluminum housings and subjected to aggressive oil additives. The use of fluoroelastomer in place of silicone material has provided improved seal performance in engine applications. An advanced crankshaft seal, incorporating a half rubber/half metal O.D. and a superior fluoro-elastomer material, has been developed to improve seal installation and retention in aluminum housings and extend seal life beyond the present seal technology.
