    Hydraulic Cylinder Oil Seal UHS/UN/UNS/U/Y/V Type Shaft Hole ...
    Hydraulic UNS seals are typically manufactured from high-performance polyurethane (PU) with a Shore hardness of 90-94A. These U-cup seals are designed for both rod and piston applications, handling pressures up to
    400
    bar
     (
    5800
    psi
    ) and temperatures ranging from
    -35∘Cnegative 35 raised to the composed with power C
    −35∘C
     to
    100∘C100 raised to the composed with power C
    100∘C
     due to their excellent wear resistance, elasticity, and durability. 
    Key Material Characteristics 
    • Material: High-Performance Polyurethane (PU/TPU).
    • Hardness: Typically 90-94 Shore A.
    • Color: Commonly blue, green, or light yellow.
    • Performance: High abrasion resistance, high pressure resistance, and good elasticity. 
    Technical Specifications 
    • Pressure Range: Up to 40 MPa (
      400
      bar
       /
      5800
      psi
      ).
    • Temperature Range:

    • Speed:
      ≤0.5
      m/s
      .
    • Media: Mineral oil-based hydraulic oils. 
    Features of UNS Seals 
    • Design: Symmetric U-cup, where the inner and outer sealing lips have the same height, making them interchangeable for piston or rod use.
    • Installation: Easy to install, often allowing for installation in integral grooves.
    • Application: Ideal for heavy-duty hydraulic cylinders. 
    Common alternatives for, or components in, these seals include TPU (Thermoplastic Polyurethane) and rubber, ensuring flexibility and longevity in industrial, high-pressure environments.
