Specifications

The DK 123D profile is a compact double-acting seal for heavy mobile hydraulic services.
It consists of a sliding ring, confined by support rings (DST 108) in the housing, which is energized by an elastomer profile. The relief of the sliding ring allows lubrication of the sliding ring, increasing the service life of the part.
- The slip ring cannot twist on itself.
- The slip ring cannot extrude.
- Good friction ring lubrication.
The slip ring can be machined in various polyurethane formulations. See materials section.
