Products Description
Rubber X-ring seal(Quad Ring) is a circular rubber sealing ring with four sealing lips, which can act as a two-way seal. X-ring has the advantages of convenience, economy, and wide application fields. Compared with the O-ring, it improves the problems of twisting, extrusion, and low performance. It can better reflect its advantages when used in the sealing system of reciprocating motion, rotary motion, and spiral motion. It has good interchangeability with the groove of the AS568 A standard series O-ring.
The rubber X-ring seal can be used in sealing gas and liquid in dynamic or static occasions, suitable for reciprocating pistons, piston rods, and plungers, and also suitable for shafts and mandrels under swinging, spiral, and rotating conditions.
Advantages
1) During reciprocating motion, it is not easy to produce spiral twist damage.
2) Due to the small radial precompression formed, the contact pressure is small and the friction force is also small, which does not easy to cause gap bites and reduces the power loss of moving parts.
3) Due to the uniform contact pressure, the leakage is small.
4) Since the parting surface of the mold is set between the two lips, the flash will not affect the sealing effect.
5) The X-shaped sealing ring will form a lubricating cavity between the sealing lips, which has small friction resistance and starting resistance.
6) Since its flash edge is located in the recess of the section, the sealing effect is good.
7) Non-circular cross-section can avoid rolling during reciprocating motion. Therefore, the X-ring has the characteristics of long life and good sealing effect in dynamic sealing occasions.
