Federal-Mogul Corporation’s National Wheel End Components brand has published a new catalog covering its expanded line of oil bath seals, premium through-hardened trailer bearings, bearing sets, hub caps, unitized wheel bearing nut systems and other components for commercial vehicles.

The new National Wheel End Catalog (No. 502W) details thousands of precision-engineered, original equipment-style components for tractor front and drive axles as well as trailer, tag and pusher axles. For the first time, the 502W catalog also features National premium through-hardened bearings for most popular heavy-duty trailer applications, as well as the industry-preferred Axilok unitized wheel bearing nut system. An expanded range of National matched bearing sets, hub caps and 37 and 38 series oil bath seals are also featured.

Federal-Mogul’s National through-hardened trailer bearings are manufactured from top-quality steel and through the same state-of-the-art equipment and processes associated with OE-style bearings. These bearings deliver superior dimensional accuracy and surface finish for ultra-low vibration and feature premium through-hardened material for outstanding strength and stability. Each bearing also features crowned raceways and matched rollers for ultra-consistent load distribution and extended service life.

National heavy-duty hub caps from Federal-Mogul are available in durable cast aluminum and chrome-plated bodies and in eight advanced designs for virtually any heavy-duty wheel end. Each National hub cap is delivered complete with a premium non-stick Fel-Pro gasket for a superior seal and fast, trouble-free installation.

The catalog also highlights the brand’s expanded offering of matched cup-and-cone bearing sets for front, drive and trailer axles. With 20 SKUs covering virtually all popular applications, the new National bearing sets enable fleets and vehicle operators to ensure exceptional wheel-end performance and durability in a broad range of operating conditions.

National oil bath seals include advanced 37 Series point-contact style units and premium 38 Series PTFE seals featuring Federal-Mogul’s patented lay-down bi-directional sealing lip.
