Looking to replace a worn oil seal but unsure whether to choose National or SKF? Or maybe you’re cross-referencing part numbers and need to find a compatible alternative?
Beide National Und SKF are trusted brands in the sealing world—but how do they compare, and which oil seal is best for your needs?
In this article, I’ll walk you through the key differences between National and SKF oil seals, how to use a cross reference chart, and whether aftermarket options like Hengoseal can match their performance.
What is the difference between National and SKF oil seals?
| Besonderheit | National® | SKF® |
|---|---|---|
| Brand Origin | USA (Federal-Mogul / Timken) | Sweden (SKF Group) |
| Industry Focus | Automotive, Heavy-Duty | Automobilindustrie, Industrie |
| Common Structure | TC, SC | CR Seals (Chicago Rawhide), TC |
| Verfügbarkeit | North America heavy use | Global OEM preference |
| Price Range | Moderate to Premium | Often higher (OEM-specified) |
National seals are widely used in trucks and trailers, while SKF is more common in OEM-level European, Asian, and American equipment.
If you’re replacing seals in Japanese cars or industrial machines, you may also consider TC-type Hengoseal oil seals that match the same specs at lower cost.
Are SKF oil seals OEM quality?
Yes—SKF is a leading OEM supplier.
SKF’s CR Seals (formerly Chicago Rawhide) are factory-installed in many vehicles from:
- Volvo
- Volkswagen
- John Deere
- Komatsu
- Toyota
SKF oil seals are known for:
- Tight manufacturing tolerances
- Premium materials (including Viton/FKM)
- Long service life under harsh conditions
However, OEM quality doesn’t always mean best value. For distributors and importers, aftermarket equivalents with OEM-level specs can save cost while maintaining performance.

How to cross reference National to SKF oil seals?
Use an oil seal cross reference chart to match dimensions and structure:
| Schritt | Action |
|---|---|
| 1. | Locate your part number (e.g. National 471763) |
| 2. | Match ID × OD × Width (e.g. 38.1 × 62.0 × 10.9 mm) |
| 3. | Identify structure (e.g. TC double lip) |
| 4. | Search SKF equivalent (e.g. SKF 15207) |
| 5. | Check material: NBR vs FKM, rubber or metal shell |
For quick matching, use our online Querverweistabelle für Öldichtungen or send us your specs for direct mapping.
