Characteristics

OSY-piston packings are applicable to low pressure and hydro-pneumatic cylinders.
OSY-piston packings slide smoothly at low pressure/speed operating conditions free from stick-slip phenomenon.

Remarks

  • ●Packings should be installed in the direction specified on the above schematic.
  • ●Consider adopting split grooves if one-piece groove is technically adverse.
  • ●φD H9/f8 changes according to the variation of the bearing structure.
  • ※JIS standard sequence of surface roughness symbols refer to HERE.
