The National Oil Bath Seal line from Federal-Mogul provides complete coverage for any commercial-vehicle replacement application and sets the standard for the industry.
National also has pioneered the design and use of polytetrafluoroethylene (PTFE) oil seals for commercial-vehicle wheel end applications. The company’s patented lay-down sealing lip design ensures long life in spite of extreme temperatures, shaft imperfections, shaft/bore misalignment and excessive shaft thrust or movement.
