X-rings
X-ring
It is a precision sealing element with a square cross-section with an "X" shaped profile that forms four sealing
edges. The dimensions of the X-ring are determined by its inner diameter "di" and the cross-section size "CS". X-rings are
supplied in dimensions according to American Standard AS568.
ADVANTAGES
Due to the "X" shape and the four sealing edges, X-rings require less initial compression compared to O-rings, resulting in reduced friction and thus wear in dynamic applications. Other advantages are:
● Square cross-section prevents rotation of the seal in the groove during assembly or straight-line movement.
● lower initial compression in dynamic applications reduces friction and wear, reducing the effect of permanent deformation and thus extending service life
● lubricant is trapped in the space created between the cutting edges, which aids perfect lubrication of the cutting edge during reciprocating straight-line motion, or during rotary or combined motion
● the cutting plane of the mould passes through the space between the blades and its quality cannot affect the function of the seal
● Similar to O-rings, simple and space-saving design, easy installation
