First, the introduction of imported star ring
1) X-ring (star) is also a standard part of the cross section for the X type seal ring. Suitable for machinery, valves, cylinders, pumps, etc.. The main specifications to American Standard AS568 as the standard, the diameter of 1.78, 2.62, 3.53, 5.33, 6.99; the spot mainly use NBR and fluorine rubber and other non-standard specifications can also be customized mold. Star ring is a kind of sealing ring with four lip cross section. The same as it o ring has the advantages of convenience, economy and wide application field etc.. Compared with O-Ring, it improves the problems such as distortion, extrusion and so on. In the reciprocating motion, rotary motion and the spiral movement of the sealing system, more can reflect its advantages. It has good compatibility with the 568A AS standard series O-Ring groove. The application of both gas and liquid in the star ring in dynamic or static sealing occasions, suitable for reciprocating piston, piston rod, piston, but also in the swing and rotation of the spiral mandrel is applied to the shaft and etc..
2) sealing pressure type X: static ring, up to 5MPA; and a retaining ring, up to 40MPA.
Dynamic, reciprocating motion without ring, up to 5MPA; the reciprocating motion of a retaining ring, up to 30MPA; rotational motion with a retainer ring, up to 15MPA;
3) motion speed: reciprocating motion, up to 0.5M/S; rotational motion can reach 2M/S.
4 temperature: the general and the chosen material, the limit temperature of VITON rubber NBR is -40~120; the limit temperature of fluorine plastic -40~240 is.
5) star ring feature:
A, anti distortion and anti extrusion better; B, double sealing lip; C, no rolling phenomenon; D, small friction resistance;
E, dynamic sealing performance is excellent.
Two, high precision imported O-ring
Taiwan Asahi Meike seal (XOK), products work fine, smooth surface, no burr, no needle, precision can reach +/-0.08 ~+/-0.03 mm. Import apron has excellent abrasion resistance, weathering resistance and high temperature (-60~250 degrees), the characteristics of ozone resistance and chemical resistance etc.. The organic liquid (oil, fuel, hydraulic oil), inorganic acid, high concentration of hydrogen peroxide and other oxidants are better stable performance. Imported O type sealing ring can be used for sealing the original, but also can be used as a hydraulic sliding seal and dust ring of the force application unit. In machinery, petrochemical industry, instrumentation, sanitary ware, medical equipment, automotive, pump valve and other industrial systems can be said that there is no need for high precision sealing ring.
Three, American Standard, Japanese standard, GB O-ring specifications available
Taiwan Asahi Meike seal (XOK), always adhere to the "quality first, customer satisfaction 100%" principle and set up factories, and continuously improve product quality, improve product varieties to meet the changing needs of the market. The main products: import O-ring, EPDM three EPDM seals, imported oil seal, O ring, sealing ring, DuPont VITON fluorine rubber O-ring, high-temperature seal, VA seal, U ring, O-ring, O-ring seal price, specifications, fluorine rubber seal size. Black NBR nitrile rubber O - ring, seal material, seal manufacturer, silicone O-ring, Y ring, PU ring, Gelailai hole ring, shaft stepseal, UHS ring, USH ring, LBH ring, UPH ring, square circle etc..
