Shaft Seal and Rubber Oil Seal.jpg

Shaft Seal and Rubber Oil Seal

A shaft seal — also known as a rotary seal or rubber oil seal — is used to retain lubrication and prevent leakage along rotating shafts. Our design integrates a stainlesssteel shell for dimensional stability and a bonded NBR rubber lip for elastic, dynamic sealing. The metal core provides rigidity during press-fit installation, while the rubber ensures a tight seal against the shaft.

    Material Available in Menhow

    Elastomeric Seal Lip (typically bonded to metal)

    NBR (Nitrile Rubber)

    Great oil resistance, good for general-purpose use

    HNBR

    Superior heat, oil, and abrasion resistance compared to NBR

    FKM (e.g., Viton®)

    High temperature and chemical resistance

    Silicone Rubber

    Excellent flexibility and thermal stability

    EPDM

    Good for water and steam resistance

    LSR

    Excellent high/low temperature resistance, flexibility, and biocompatibility
    01020304

    Metal Case or Reinforcement

    SUS (Stainless Steel)

    Corrosion-resistant, durable, commonly used in high-moisture or chemical exposure environments

    Carbon Steel

    More cost-effective for standard industrial use

    Our Advantages

    Menhow’s shaft seal combine the strength of stainless steel (SUS) with the flexibility and chemical resistance of nitrile rubber (NBR) to deliver reliable, long-lasting performance in high-speed and harsh environments. Designed as metal-rubber composite seals, they are engineered to prevent fluid leakage, block contaminants, and maintain seal integrity under pressure and rotation.

    Dual-material construction

    Combines the structural strength of SUS with the sealing performance of NBR

     Excellent oil and fluid resistance

    NBR rubber resists common lubricants, fuels, and hydraulic fluids

    Robust mechanical stability

    Stainless steel casing supports press-fit installation without deformation

    Wear-resistant sealing lip

    Maintains a tight seal under rotary motion and shaft misalignment

    Customizable design

    Available in various cross-sections, lip geometries, and dimensions

    Reliable sealing under pressure

    Withstands internal pressures and shaft speeds common in automotive and industrial applications
