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.
