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
