Characteristics
OSD-piston packings are applicable to low pressure and hydro-pneumatic cylinders.
Unique double acting one-ring profile with seal lip provides similar sealing performance that allows compacter piston part.
OSD-piston packings are compatible with PSD & PPD-Packings, pneumatic seals.

Remarks
- 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.
