4. Adantage:
• Due to application-optimized geometry and compounds suitable for use in oiled
as well as in oil-free air (after initial lubrication on assembly).
• Bi-functional element: seal and wiper.
• Extreme wear resistance.
• Low static and dynamic friction thanks to miniaturized design.
• Smooth running due to optimum adjustment of the functional lips.
• Smooth running due to optimum lubricant-retaining sealing lip geometry.
• Excellent media resistance in case of suitable compound selection.
• Short axial assembly length.
• Short radial assembly depth.
• Installation in closed and undercut housings.
• Low compression set.
• The coordinated geometries of the seal and wiper lips achieve favourable friction coefficients and long service life.
5. Product Specification:
6. Installation:
The self-retaining rod seal/wiper profile DHS is manually or automatically snapped into
the installation housing while the piston rod is disassembled. Care is to be taken to
prevent sharp edges from damaging the wiping and sealing lips during assembly.
Initial lubrication is the prerequisite for very long operational life.
