National Oil Seal Wheel Bearing Collar

National Oil Seal Wheel Bearing Collars: Precision at the Wheel End

When it comes to wheel end integrity, few components are as quietly critical as the wheel bearing collar. Acting as a precision interface between the bearing assembly and the spindle or axle shaft, a bearing collar ensures the bearing is properly seated, retained, and protected against axial movement. Choosing the right collar — from a manufacturer that understands the demands of the wheel end environment — makes all the difference in long-term reliability and safety.

National Oil Seal brings decades of engineering heritage to this specialized component. National, now operating under the Tenneco/DRiV family of brands, earned its reputation as a premier wheel end supplier after Federal-Mogul acquired the National Seal Division of the National Motor Bearing Company — a move that catapulted Federal-Mogul into the Fortune 500 on the strength of National's market leadership. That legacy of precision sealing and bearing technology carries directly into their wheel bearing collar lineup.

Engineered to OE Standards — and Beyond

National's wheel bearing collars are held to the same rigorous standards as the rest of their wheel end product family. Key engineering principles that define these parts include:

• OE-matching load ratings: Element size and geometry are engineered to meet or exceed the load ratings of original equipment bearings, ensuring that the collar works in harmony with the bearing rather than becoming a weak link.
• Comprehensive vehicle coverage: National offers industry-leading application coverage across domestic and import platforms, making it easier to find the correct collar for a wide range of makes and models.
• Rigorous development testing: Every product in the National lineup undergoes comprehensive testing throughout the design and development process — not just at the end of the line — so quality is built in from the start.
• Premium materials: National's wheel end components are constructed from premium steel, providing a superior and durable solution for demanding wheel end environments.

Why National Stands Apart in the Wheel Bearing Collar Category

The wheel bearing collar is a high-stress part that must endure constant rotation, thermal cycling, and exposure to road contamination. National's long history in precision sealing and bearing technology means their collars are designed with an understanding of the entire wheel end system — not just the collar in isolation. Their engineers consider how the collar interacts with seals, bearing races, and hub lubricants to deliver a part that protects the full assembly.

National currently offers two wheel bearing collar part numbers in this category (including part numbers such as 510029 and 510089), covering a focused but important range of applications for both passenger car and light-duty vehicles. Whether you are performing a routine wheel bearing service or addressing wear discovered during an inspection, National's collars provide the consistent, reliable fit that professional technicians and serious DIYers depend on.
