Characteristics

PPD-Packings are double acting piston packings which is designed to provide high followability to eccentrical movement and retain high durability and wear resistant property.
PPD-Packings are interchangeable with PSD-Packings.

Remarks

  • ●Consider adopting split grooves if one-piece groove is technically adverse.
  • ●φD H9/f8 would be modified 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 with D diameter φ40 and smaller sizes, the torelance of G dimension was updated to achieve better performance.
  • ※JIS standard sequence of surface roughness symbols refer to HERE.
