SEG Rod Seal

SEG Series Tri-Material Piston & Rod Seals | All-Pressure Hydraulic Solutions

Precision-engineered for ultimate reliability, the SEG Series Hydraulic Cylinder Rod Seal combines NBR/FKM elastomers, fabric reinforcement, and precision-molded POM into a revolutionary U-cup design. Its integrated rubber energizer delivers zero-leak performance from vacuum conditions to 40 MPa while reducing friction by 45% versus conventional rod seals.

Core Technical Specifications

Performance Advantages

1. Dual-Pressure Mastery

• Low-Pressure Sensitivity: Maintains 0.2N/mm² contact force at 0.5 MPa

• High-Pressure Integrity: Fabric reinforcement withstands 40 MPa extrusion (ISO 10766-1 validated)

2. Tri-Material Synergy

• POM Guide Band: Reduces friction coefficient to ≤0.05 (ASTM D1894)

• Fabric Reinforcement: Prevents blowout in pressure spikes

• NBR/FKM Energizer: Auto-adjusts lip force across temperatures

3. Critical Applications

• Mobile Hydraulics: Excavator boom cylinders (resists mud/emulsions)

• Food Processing: Stainless steel washdown pumps (FDA-compliant FKM)

• Energy: Hydraulic pitch control systems in wind turbines

Installation & Operational Benefits

Installation Advantages

• 3-minute snap-fit installation (vs. 15+ min for tandem seals)

• Single-unit design eliminates stacking errors

Damage Prevention Protocol

1. Groove Requirements: ISO 5597-1 profiles with Ra≤0.8μm finish

2. Edge Safety: Mandatory 0.5mm chamfer (DIN 3761)

3. Lubrication: Use water-soluble greases for water-based media

Failure Prevention Features

• POM band prevents metal-to-metal contact

• Anti-torsion fabric alignment ribs
