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 conditons -in both regular and severe cold euvironments- 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 theabove schematic.
●Consider adopting divided grooves if one-piece groove is technically adverse.
●φD H9/f8 would be modified according to the variation of the bearing structure.
