?Star hydraulic seal profile

??Star hydraulic seal is a standard member, the cross-section X hydraulic seals. For machinery, valves, cylinders, pumps. Specifications subject mainly to American Standard AS568, diameter of 1.78,2.62,3.53,5.33,6.99; spot mainly NBR and fluorine-based rubber, other non-standard specifications can also be custom mold. Star hydraulic seal is a four-lip seal cross section. With o-ring as it is convenient, economical and widely application field so on. Compared with the O-ring, which improves the distortion, extrusion and other issues. In reciprocation, rotary motion and spiral motion sealing system used, to better reflect its superiority. It trench AS 568A standard series O-ring has a good interchangeability. Star ring seal hydraulic gas, liquid can be applied in the case of dynamic or static, suitable for reciprocating motion of the piston, the piston rod, piston, but also in the swing screw shaft and rotating condition applies and the mandrel and the like.

??2) X Hydraulic seal Working pressure: no static ring, up 5MPA; when ring, up 40MPA.

??Dynamic, reciprocates no ring, up 5MPA; reciprocation have Collar, up 30MPA; rotary motion has Collar, up 15MPA;

??3) velocity: reciprocates up to 0.5M / S; up rotational motion 2M / S.

??4) Star hydraulic seal temperature: generally the choice of material determines, NBR NBR limit temperature is -40 ~ 120 ?; fluorine rubber VITON limit temperature is -40 ~ 240 ?.

??5) Star hydraulic seal Features:

??a, anti-distortion and anti-extrusion is better; b, double lip; c, no roll phenomenon; d, friction is small;
