X-ring在使用性能上有了很大的提高和改进，不管是用于活塞或活塞杆都能起到良好的密封效果，能够替代O型圈来使用。此外，因X-ring的规格尺寸和公差标准与美国的AS568A标准的O型圈替代使用。
X-ring与O型圈相比，由于其在密封唇之间形成润滑容腔，具有较小的启动阻力和的摩擦阻力。
由于它的飞边位置在截面的凹处，也就是两个密封唇之间，且远离唇口位置，所以密封效果非常好。
因其采用的是四个密封唇口的非圆形截面，因此在往复运动中沟槽不易扭曲，因而不会产生滚动。
由于X-ring拥有更小的压缩量，因此摩擦力会很小，从而拥有更长的使用寿命。
因为其截面拥有较好的压力分布，因此能够获得好的密封效果。
X-ring是一种自紧密封型的双作用密封件，径向与轴向上的力取决于系统的压力，当安装在各种形式的沟槽中其径向或轴向预压缩赋予X-ring初始密封能力，随着压力的上升，X-ring的压缩变形会增大，截面形状会使压力向各个方面均匀的传递，总的密封力随着提高，从而达到稳定的密封效果。X-ring根据使用场合的温度、压力及介质来选择合适的规格与材质。
温度范围：一般场合-30~110℃;特殊材料-60~200℃;旋转场合-30~80℃
工作压力：有挡圈(动密封时往复运动30Mpa，旋转运动15Mpa)无挡圈(动密封时往复运动5Mpa,静密封时5Mpa)
运动速度：往复运动0.5m/s;旋转运动:2.0m/s;
硬度范围：邵氏A硬度40度~90度
外观颜色：常见的有黑色蓝色棕色橙色等，也可由客户指定。
X-ring的应用范围非常广泛，可适用于各种机械设备上，在规定的温度、压力、以及不同的液体和气体介质中，于静止或运动状态下起密封作用。主要用于动密封，如密封往复运动的活塞、活塞杆、柱塞及密封摆动、旋转或螺旋运动的轴或心轴。也有用于静密封，如径向静止的工件，如套筒、端盖、管以及轴向静止的工件，如法兰、盖板等
X-ring has been greatly improved and improved in performance. Whether it is used for piston or piston rod, it can play a good sealing effect and can completely replace O-ring. In addition, the specifications, dimensions and tolerances of the X-ring are exactly the same as the American AS568A standard O-ring.
main feature:
Compared with O-rings, X-rings have lower starting resistance and lower frictional resistance due to the lubricating cavity formed between the sealing lips.
Because its flash edge is located in the concave part of the section, that is, between the two sealing lips, and is far away from the lip position, the sealing effect is very good.
Because of the non-circular cross-section of the four sealing lips, the groove is not easily twisted during the reciprocating motion, so there is no rolling.
Because the X-ring has less compression, there is less friction, resulting in a longer service life.
Because its cross-section has a good pressure distribution, it can obtain an excellent sealing effect.
Sealing principle:
X-ring is a self-tightening double-acting seal. The radial and axial forces depend on the pressure of the system. When installed in various forms of grooves, its radial or axial pre-compression gives X -The initial sealing ability of the ring, as the pressure rises, the compression deformation of the X-ring will increase, the cross-sectional shape will make the pressure evenly transmitted to all aspects, and the total sealing force will increase, so as to achieve a reliable sealing effect. X-ring selects appropriate specifications and materials according to the temperature, pressure and medium of the application.
Performance parameters:
Temperature range: general occasion -30~110℃; special material -60~200℃; rotating occasion -30~80℃
Working pressure: with retaining ring (reciprocating motion 30Mpa during dynamic sealing, 15Mpa rotating motion) without retaining ring (reciprocating motion 5Mpa during dynamic sealing, 5Mpa during static sealing)
Movement speed: reciprocating movement 0.5m/s; rotary movement: 2.0m/s;
Hardness range: Shore A hardness of 40 degrees to 90 degrees
Appearance color: black, blue, brown, orange, etc. are common, and can also be specified by customers.
Industry use:
The application range of X-ring is very wide, and it can be applied to various mechanical equipment, under the specified temperature, pressure, and different liquid and gas media, it can play a sealing role in static or moving state. Mainly used for dynamic seals, such as sealing the reciprocating piston, piston rod, plunger and sealing the shaft or mandrel for oscillating, rotating or helical motion. It is also used for static sealing, such as radially static parts, such as sleeves, end caps, pipes, and axially static parts, such as flanges, cover plates, etc.
