Characteristics

KY-Packings available in abundant dimensions. With the large cross-sectional area,
KY-Packings provide stable sealing performance in vast applications.

Remarks

  • ●Packings should be installed in the direction specified on the above schematic.
  • ●Adopt split grooves. However, note that D=140 for pistons and larger sizes, and d=80 for rods and larger sizes are installable in one-piece groove.
    For these cases, specify back-up rings with bias cut (TC-KY-○○). Besides, one piece groove can be technically adverse for some groove locations.
  • ●φD H9/f8 changes according to the variation of the bearing structure. For applications installed in combination with wear rings, refer to the dimension table of the applicable wear rings.
  • ※For applications without back-up rings, refer to the limiting curve of extrusion of seals for size (φd2)
  • ※JIS standard sequence of surface roughness symbols refer to HERE.
