FEATURES
RS07 is a two-piece rod seal profile designed for high-performance hydraulic sealing applications. It consists of a polyurethane sealing ring paired with an O-ring energizer, ensuring excellent sealing capability under varying pressures and temperatures.
COMPOSITION
| Seal Combination | Seal Ring Compound | Square Energizer | Temperature Range | Working Pressure (Max.) | Surface Speed (Max.) |
|---|---|---|---|---|---|
| RS07 | PUR04 / PTF02 | NBR01 | -35 to 102°C | 325 Bar | 0.5 m/s |
| RS07 | HYL03 | NBR01 | -35 to 102°C | 325 Bar | 0.5 m/s |
EXTRUSION GAP DIMENSION
The radial gap on the non-pressurised side of the seal plays a critical role in ensuring effective sealing performance. The figures provided indicate the maximum permissible radial clearance on each side, calculated based on the maximum inner diameter of the gland bush groove and the minimum rod diameter, taking into account their respective manufacturing tolerances.
| Profile Dimension (H) | Max. Permissible Gap (S) at 160 bar | Max. Permissible Gap (S) at 260 bar | Max. Permissible Gap (S) at 320 bar |
