Characteristics
ⓉSGY-piston packings are interchangeable with SKY-Packings.
Broad service temperature range of -45℃ to +100℃ allows cylinders for use in international cold environments without changing packings.
They also feature exceptionally low stick-slip.
High pressure and/or high frequency conditions should be avoided due to the material RN812, moderately low in rubber hardness.

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.
- ●Do not use in single acting.
- ※JIS standard sequence of surface roughness symbols refer to HERE.
