HLAVNÍ VLASTNOSTI

The "SHT" is the optimal solution for industrial hydraulic applications. It can be used in the same housing normally destinated to PTFE seal of which has similar technical and dimensional characteristics but, compared to it, better sealing capabilities, greater ease of installation and a lower cost.

The "SHT", composed of a high resistance polymer element on the dynamic side and an O-ring as energizing component on the static side, can be used:

- individually
- in tandem: prefereable solution in the presence of rapid and high pressure variations.

  • Good sealing performance
  • Low cost compared to the corresponding PTFE seal
  • Easy installation
  • Low friction and no tendency of stick-slip
  • Returns to the size immediately after assembly
  • Simple groove design and space-saving construction
  • Excellent wear-resistance
  • High resistance against extrusion
  • Extended service life
  • Good temperature resistance

GAP DIMENSION "G"

The largest gap dimension appearing [mm] in operation on the non-pressurised side:

L 100 bar 200 bar 300 bar 400 bar
2.2 0.70 0.45 0.35 0.30
3.2 0.80 0.50 0.40 0.30
4.2 0.80 0.50 0.40 0.35
6.3 0.90 0.55 0.45 0.35
8.1 1.10 0.70 0.50 0.40

> 400 bar => gmax = H8/f8

  • Abyste předešli poškození těsnění, zástavba musí mít zkosené hrany.
  • Ostré hrany a otřepy v instalační oblasti je třeba odstranit.
