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.
Looking for high-strength applications? Explore our TG4 스켈레톤 오일 씰 with dust lip protection.
What types of skeleton oil seals are available?
There’s no one-size-fits-all in dynamic sealing. Each application requires a tailored design.
| 유형 | 구조 | 더스트립 | 일반적인 사용 |
|---|---|---|---|
| TG4 | 더스트립이 있는 더블립 | ✅ | 모터, 펌프, 기어박스 |
| 티씨티 | 금속 쉘이 있는 더블립 | ❌ | 표준 산업용 |
| K형 | 컴팩트한 프로필 | ❌ | 좁은 주택, 공간 제한 지역 |
| 분할형 | Open-style, easy install | ✅ | Field repairs and maintenance |
우리의 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.
| 재료 | 전체 이름 | 속성 | 사용 사례 |
|---|---|---|---|
| 영어: NBR (네이버) | 니트릴 고무 | 내유성, 저렴, -40°C ~ +120°C | Motors, compressors, low-temp |
| 에프케이엠 | 불소고무 | 내열성 및 내화학성, -30°C ~ +200°C | Gearboxes, engines, high-temp |
우리의 FKM 씰 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:
- 전기 모터
- 유압 펌프
- Automotive crankshafts
- Gearboxes
- Industrial fans and blowers

How do I choose the right type?
Use this checklist to avoid mismatches:
| 요인 | 확인할 사항 |
|---|---|
| 샤프트 직경 | Must match seal’s inner diameter |
| Housing Bore | Fit outer diameter tightly |
| Speed Rating | NBR ≤15 m/s, FKM supports higher speeds |
| 온도 | 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.
결론
Skeleton oil seals combine durability, stability, and high sealing integrity. The right type ensures reliability across electric, hydraulic, and rotating systems.
