The National Seals® is a proud designer and supplier of wheel bearings and oil seals with a focus on quality, safety, and continuous improvement. The key to its success may be attributed to its hardworking and dedicated team of engineers who keep pace with the industry to provide premium wheel end solutions for light and commercial vehicle applications. Federal-Mogul acquired the National Seal Division of the National Motor Bearing Company only in 1942. But the brand National Seals has already cemented itself as one of the most respected names in the industry. Over the years, it has remained fully committed to providing only the highest quality seals and bearings that meet or exceed OE specifications.
