T-SGY Hydraulic Seal Hydraulic packings for piston（Installable in one-piece groove）
The groove dimensions of SGY & SNY packings are compatible with those of the SKY-packings.
Service temperature range of －45℃ to +100℃ allows cylinders for use in multiple temperature conditions -in both regular and severe cold environments- without changing packings.
SGY & SNY-packings also feature exceptionally low stick-slip. Due to the nature of the application, the material is required to have a moderately low material hardness.
Conduct verification tests in the case of SGY & SNY-packings are used in high pressure and/or high-frequency conditions.
- Packings should be installed in the direction specified in the above schematic.
- Consider adopting divided grooves if the one-piece groove is technically adverse.
- φD H9/f8 would be modified according to the variation of the bearing structure.
