Professional O-Ring and Oil Seal Manufacturer, Sealing Solution Supplier Since 2008.
High - Performance TCV Skeleton Oil Seal for Rotating Machinery
Excellence in Sealing, Pressure Resistance, and High - Speed Operation
Engineered for rotating machinery, the TCV Skeleton Oil Seal excels in sealing efficiency, with a main lip stopping oil leakage and a dust lip blocking external contaminants. It withstands up to 0.3MPa pressure and operates smoothly at high speeds—thanks to its low-friction single-lip design.
The inner metal skeleton boosts rigidity, while the outer rubber body ensures stability even in high-temperature environments. Ideal for engines, gearboxes, etc., it serves automotive, chemical, and machinery sectors. Durable and reliable, it minimizes maintenance needs, extending equipment lifespan and delivering long-term sealing value.

1. Product Advantages
Our TCV Skeleton Oil Seal delivers long-lasting reliability with 0.3MPa pressure resistance, making it suitable for medium-pressure rotating machinery and preventing lip deformation. Its low-friction single-lip design minimizes heat generation, enabling high-speed operation that outperforms the average of standard oil seals. It also tolerates temperatures ranging from -20°C to 120°C, adapting well to fluctuating temperature conditions.
The dual-protection system (main sealing lip + dust lip) effectively blocks oil leakage and keeps out contaminants such as dust and sand. This design reduces maintenance frequency by up to 30%, extends the service life of both the seal and the associated machinery, and lowers long-term operational costs.
2. Working Principle
The seal’s performance relies on a synergistic structure: the inner high-strength galvanized steel skeleton ensures structural rigidity, preventing warping and gaps during installation and operation.
The outer rubber body (available in NBR or FKM options) features a main lip with a built-in spring. This spring applies consistent radial force, maintaining tight contact with the rotating shaft even when the shaft experiences minor vibrations or thermal expansion. The outward-facing dust lip scrapes off surface contaminants and creates an air buffer zone, guaranteeing reliable sealing performance in dynamic working conditions.
3. Product Details
Material: High-grade nitrile rubber (NBR) for general industrial use (excellent oil resistance and flexibility) or fluororubber (FKM) for harsh environments (superior chemical resistance and heat tolerance); galvanized carbon steel skeleton for enhanced corrosion resistance.
Precision: The inner skeleton is fully encapsulated in rubber to prevent rust transfer; the outer rubber has a smooth finish for easy installation; the main lip features a precision-cut edge; dimensional tolerance is controlled within ±0.05mm.
Testing: Every TCV Skeleton Oil Seal undergoes three key tests before leaving the factory: a 0.3MPa pressure test, a high-speed rotation test, and a temperature cycle test (-20°C to 120°C) to ensure consistent quality.

4. Application Range
It is a versatile solution for rotating machinery across multiple industries:
Automotive Industry: Used in engines (crankshafts, camshafts), transmissions (gearboxes, differential shafts), and auxiliary systems (water pumps, alternators).
Chemical Industry: Ideal for mixers, agitators, and pump shafts in chemical processing plants (FKM variant resists oils, solvents, and mild corrosive fluids).
Machinery Manufacturing: Suitable for industrial motors, conveyors, and printing machinery that operate continuously at moderate to high speeds.
Oil & Gas Industry: Applied in small to medium-sized pumps and compressors in upstream and downstream operations.
It fits standard shaft diameters ranging from 15mm to 100mm and can also be customized to match specific shaft sizes.
5. FAQ
Q: What is the maximum rotational speed the TCV Skeleton Oil Seal can handle?
A: The maximum safe rotational speed is 8m/s for standard NBR models and 10m/s for FKM models. However, speed performance may vary based on shaft diameter, temperature, and lubricant type. Our engineering team can provide customized speed recommendations based on your specific equipment parameters upon request.
Q: What tips should be followed for proper installation to ensure optimal performance?
A: First, clean the housing groove and shaft surface to remove debris. Then, apply a thin layer of compatible lubricant (e.g., mineral oil) to the seal lip and housing to reduce friction during installation. Finally, use a press tool or installation sleeve to push the seal into the groove evenly, avoiding uneven force that could damage the lip. A detailed installation guide with step-by-step diagrams is included with every order, and our technical support team is available via phone or email for installation troubleshooting.
Q: What is the expected service life of the TCV Skeleton Oil Seal?
A: Under normal operating conditions (proper installation, compatible lubricant, temperature within -20°C to 120°C), the expected service life is 2,000 to 3,000 operating hours for industrial machinery and up to 50,000 kilometers for automotive applications. Regular equipment maintenance and adherence to operating guidelines can further extend its service life.
