Description
    With tension spring
    With protective lip
    Shortened sealing lip
    Rubberized outer jacket
Advantages
    Very good static sealing effect with low-viscosity or gaseous media.
    High chemical resistance
    No stick-slip effect
    Compensation of thermal expansion, e.g. in light metal housings, very good sealing effect with greater roughness and split housings
    Longest service life
Function
    Dynamic sealing of rotating shafts, independent of direction of rotation
    Shortened sealing lip allows higher operating pressure
    Good static seal between sealing lip and shaft at standstill
    Protective lip against dirt accumulation from outside
    Rubberized outer jacket ensures tight fit and seal to housing bore
    Self-retaining
    Stronger friction can lead to temperature increase
Applications
    Pressurized units such as hydraulic pumps, motors and hydrodynamic couplings
