RS PTFE Rubber Hydraulic Seal

RS Series Ultra-High Speed PTFE Rod Seals | Precision Hydraulic Seals for Servo Systems

Engineered for demanding dynamic applications, the RS Series Piston Rod Seal delivers unmatched performance in high-speed hydraulic cylinders up to 4 m/s. Combining bronze-reinforced PTFE seals with temperature-adaptive O-rings, this solution masters extreme conditions from -30°C to +180°C while maintaining near-zero friction.

Critical Performance Advantages

1. Extreme Environment Resilience

• 180°C Capability: FPM O-rings maintain seal integrity in foundry equipment

• Low-Friction PTFE: 50% less breakaway force vs. polyurethane seals

• Oil Film Control: Patented lip geometry prevents fluid starvation at 4m/s

2. Industry-Specific Solutions

• Servo Cylinders: Zero stick-slip in robotic welding arms

• Construction Machinery: 40 MPa shock load resistance in excavator rams

• Semiconductor: USP Class VI certification for wafer scanner hydraulics

3. Material Science Innovation

• PTFE+bronze composite reduces wear by 65% in abrasive emulsions

• Dual O-ring options cover -30°C (arctic cranes) to 180°C (die casting machines)

Installation & Configuration

Groove Requirements

• Rod Diameter <30mm: Mandatory open groove design

• Rod Diameter ≥30mm: Standard closed grooves acceptable

Installation Protocol

1. Edge Preparation: 20° chamfer on all grooves (DIN 3761 standard)

2. Surface Finish: Hardened rods (0.1-0.4μm Ra) with chromium/cermet coatings

3. Damage Prevention: Use split installation sleeves for small diameters

Ordering Reference

• Standard: RS-100

• Custom: RS-100 115.5 6.3

• Parker Interchange: CS2036M0

Why Engineers Specify RS Seals

• Zero-Leak Guarantee: 10,000 pressure cycles at 40 MPa (ISO 10766-1 validated)

• Chemical Immunity: Resists water-glycol degradation 3x longer than NBR

• Speed Advantage: Only rod seal supporting 4m/s without lubrication gaps

Compliance: RoHS 3, REACH, USP Class VI (file #VC-0052)
