DNS is a single-acting or double-acting piston rotary seal consisting of a PTFE-filled friction ring and a pre-tightened rubber o-ring. It is commonly used with guide rings. Double acting piston seals for pivot movement in hydraulic systems; housing for ISO 7425/1 compliance; preferably for hydraulic connections and rotary connections. Rotary hydraulic transmission exists in engineering machinery, engineering machinery and other industries

And mobile devices. It seals the rod, shaft, pin, rotary distributor, hydraulic motor and rotary joint for rotary or swing movement. Double-acting rotary seal can withstand double-sided pressure or alternating pressure. Installed in a groove conforming to ISO 7425. Single-acting structure with higher speed.

DSH Seals’ DNS, or “rotary seal”, provides reliable and durable radial seal. These radial seals have very low friction coefficient to ensure the best long-term sealing.

In addition, the “rotary seal” with high pressure resistance (about 30 MPa) can withstand the sharp rise in temperature and is completely free from the stick-slip effect.

 

characteristic

  • Low friction coefficient; There is no stick-slip effect at startup.

  • Excellent wear resistance and extrusion resistance.

  • The groove provides an integrated lubrication system.

  • Excellent dimensional stability.

  • Highly resistant to hydraulic oil.
