Oil Seal
An oil seal—often called a radial rotary seal, shaft seal, or lip seal—is engineered to prevent fluids (like lubricants) from leaking through rotating shafts and housings. By maintaining a tight barrier against contaminants, these oil seals enhance the durability, reliability, and performance of motors, pumps, gearboxes, and various machinery components.
At Hengoseal.com, we specialize in diverse skeleton oil seals and skeleton-free oil seals. Our portfolio includes high-pressure options, dust-proof variants, and specialized designs catering to different operating conditions—ensuring you get a radial rotary seal that perfectly matches your needs.
Product details
- TG4 Skeleton Oil Seal (NBR/FKM)
Robust design for reliable sealing in both common (NBR) and higher-temperature (FKM) environments. - Split Opening Skeleton Oil Seal (NBR/FKM)
Simplifies installation by allowing it to be split, ideal for equipment where disassembly is difficult. - K Type Skeleton Oil Seal (FKM)
High-heat, chemical-resistant solution recommended for harsh industrial applications. - EC End Cap (NBR)
A convenient seal alternative designed to close off shafts or housings without needing a traditional lip structure. - DKB Skeleton Dust Seal (NBR)
Effective dust-blocking construction for environments where particulate contamination is a concern. - GA Skeleton Dust Seal (NBR)
Similar to DKB but featuring a slightly different geometry for specific machinery requirements. - VD Seal (NBR/FKM)
Offers dependable fluid control for moderate to high-speed rotary shafts. - VS Seal (NBR/FKM)
A versatile variation of the VD Seal, suitable for diverse operating conditions and shaft sizes. - Z Type Seal (NBR)
Engineered for general-purpose applications, combining simplicity and cost-effectiveness. - J Type Skeleton-Free Oil Seal (NBR)
Eliminates the need for a rigid skeleton; excels where flexible sealing solutions are required. - Y Type Molding Seal (NBR/FKM)
Precision-molded seal for maintaining a tight fit in demanding rotary applications. - TCV High-Pressure Oil Seal (NBR/FKM)
Built for extreme pressures and higher temperatures, ensuring optimal performance under stress.
Materials & Their Advantages
- NBR (Buna-N): Excellent resistance to oils, fuels, and many fluids; cost-effective for standard industrial settings.
- FKM (Viton®): Superior chemical and heat resistance, suitable for high-temperature or corrosive environments.
Each seal type can be tailored with the right material to match your specific application requirements, from moderate temperatures to heavy-duty operations.
Where Are Oil Seals Used?
Radial rotary seals find extensive use in:
- Automotive (e.g., engine crankshafts, transmissions)
- Industrial Pumps and Gearboxes (preventing lubricant leakage)
- Motors and Generators (keeping contaminants out)
- Machinery and Conveyors (handling rotational movement in dusty or wet conditions)
Their versatile design and robust sealing properties minimize friction, reduce wear, and extend equipment life—an essential factor for maximizing efficiency in industrial and automotive systems.
