Struggling with oil leaks, dust intrusion, or short-lived seals? It might be time to switch to a skeleton oil seal—a trusted solution in high-speed and high-pressure systems.
Skeleton oil seals provide enhanced shaft sealing with internal metal reinforcement, extending service life and performance.
Read on to learn what they are, how they work, and how to choose the right type for your machinery.
What makes a skeleton oil seal different from a standard seal?
Unlike regular rubber seals, a skeleton oil seal includes a metal insert that reinforces the sealing structure.
This “skeleton” helps maintain lip pressure and positioning even under misalignment, pressure, and rotation.
Also known as radial shaft seals, they combine flexibility from rubber (NBR or FKM) with the strength of steel—ideal for motors, pumps, and gearboxes.

What types of skeleton oil seals are available?
There’s no one-size-fits-all in dynamic sealing. Each application requires a tailored design.
| Tip | Yapı | Toz Dudak | Ortak Kullanım |
|---|---|---|---|
| TG4 | Toz dudaklı çift dudak | ✅ | Motorlar, pompalar, dişli kutuları |
| TC | Metal kabuklu çift dudaklı | ❌ | Standart endüstriyel kullanım |
| K-Tipi | Kompakt profil | ❌ | Dar konutlar, alan kısıtlılığı |
| Bölünmüş Tip | Open-style, easy install | ✅ | Field repairs and maintenance |
Bizim TC Skeleton Oil Seal is ideal for standard rotation sealing without dust interference.
Which materials are used in skeleton oil seals?
Rubber alone isn’t enough. Material choice defines durability and performance.
| Malzeme | Ad Soyad | Özellikler | Kullanım Örneği |
|---|---|---|---|
| NBR | Nitril kauçuk | Yağa dayanıklı, uygun fiyatlı, -40°C ila +120°C | Motors, compressors, low-temp |
| FKM | Floroelastomer | Isıya ve kimyasallara dayanıklı, -30°C ila +200°C | Gearboxes, engines, high-temp |
Bizim FKM Contaları are ideal for chemical and thermal extremes. NBR fits general industry needs.
Where are skeleton oil seals commonly used?
Skeleton oil seals are standard in:
- Elektrik motorları
- Hidrolik pompalar
- Automotive crankshafts
- Gearboxes
- Industrial fans and blowers

How do I choose the right type?
Use this checklist to avoid mismatches:
| Faktör | Ne Kontrol Edilmeli |
|---|---|
| Mil Çapı | Must match seal’s inner diameter |
| Housing Bore | Fit outer diameter tightly |
| Speed Rating | NBR ≤15 m/s, FKM supports higher speeds |
| Sıcaklık | Use FKM above 120°C |
| Media Resistance | FKM needed for fuel/solvent exposure |
| Dusty Conditions | Use types with dust lips (TG4, Split) |
For tough environments, we recommend the TG4 double-lip design with NBR or FKM rubber.
Çözüm
Skeleton oil seals combine durability, stability, and high sealing integrity. The right type ensures reliability across electric, hydraulic, and rotating systems.
