S8 Series Reinforced Fabric Rod Seals | High-Low Pressure Hydraulic Solutions
Engineered for extreme pressure versatility, the S8 Series Piston Rod Seal combines NBR/FKM elastomers with precision-laminated fabric reinforcement to master both low-pressure precision and high-pressure stability. Its patented U-ring structure – embedded with a rubber energizing element – delivers unmatched reliability in industrial hydraulics while maintaining exceptionally low friction.
| Parameter | Specification |
|---|---|
| Construction | Fabric-laminated "U" ring + rubber energizer |
| Materials | NBR/FKM composite + graded fabric reinforcement |
| Pressure Range | 0.5-50 MPa (seals reliably from vacuum to ultra-high pressure) |
| Friction Coefficient | ≤0.08 (60% lower than standard seals) |
| Key Features | • Zero-leak sealing at 0.1 MPa • Extrusion resistance at 50 MPa • Single-piece installation |
1. Dual-Pressure Optimization
Low-Pressure Sensitivity: Energizer maintains 0.15N/mm² lip force at near-vacuum
High-Pressure Stability: Fabric reinforcement withstands 50 MPa spikes (validated in forging press tests)
2. Application-Specific Excellence
Machine Tool Spindles: Eliminates stick-slip in <1m/s precision movements
Mobile Hydraulics: Resists fabric delamination in excavator swing motors
Paper Mill Cylinders: Laminated structure prevents steam penetration at 120°C
3. Industrial Longevity
3× longer service life vs. monolithic seals in abrasive environments
100,000+ pressure cycles in ASTM D4169 transport simulation
Non-Negotiable Requirements
Groove Finish: ≤Ra 1.6μm (ISO 1302) with 0.2mm min. edge radius
Installation Torque: 1.5-3.0 N·m (use calibrated torque wrench)
Contamination Control:
Wipe grooves with lint-free IPA wipes
Never lubricate fabric layers
Damage Prevention Measures
Use split installation cones for diameters <25mm
Apply temporary PTFE tape on sharp threads
Verify groove DIN 3771/ISO 5597 compliance
Proven Applications
Steel mill hydraulic decalers (50 MPa shock loads)
Agricultural combine harvester cylinders
Pulp processing machinery with acidic media
Ordering Reference
Standard: S8-100F (FKM variant for chemical resistance)
NBR Economy: S8-100N
Custom Sizes: S8-[Diameter]_[Height]
Compliance: REACH Annex XVII, RoHS 3, ISO 3601-3
*Warning: Non-compliant installation voids 24-month warranty*
