New National ‘Red’ 37 Series Oil Seal Helps Increase Wheel-End Reliability


Federal-Mogul Corporation has introduced an innovative National heavy-duty oil seal technology that offers maximum contaminant exclusion for the toughest wheel-end applications.
Available in March through leading commercial-vehicle parts distributors, the new National “Red” 37 Series wheel seal features Federal-Mogul’s exclusive National Dynamic Edge technology, a patent-pending innovation that deflects contaminants from the seal and other wheel-end components. The National Dynamic Edge design consists of an integral sinusoidal wave that actively sweeps and propels environmental contaminants away from the seal face.
“The National brand’s Dynamic Edge technology brings an entirely new level of protection to the vehicle wheel-end,” said Laura Teste, product director, underhood products, Federal-Mogul. “Federal-Mogul engineers designed not only a fourth contaminant barrier point, but a feature that no other seal manufacturer has incorporated. The Dynamic Edge innovation will help fleets and owner-operators eliminate another leading cause of premature seal and bearing failure.”
In addition to the National Dynamic Edge technology positioned along the seal’s circumference, the new “Red” 37 Series seal features include a labyrinth design of four floating points of contact that lock out dirt and moisture and help ensure maximum service life. The spring-loaded sealing lip, manufactured from abrasion-resistant nitrile, delivers positive sealing with minimal shaft interference. The seal’s unitized construction provides increased structural integrity, and a unique inside diameter and outside diameter design¬†further resists contamination and prevents bore and shaft leaks.
