The CS09-E is a high-performance asymmetric composite rod seal, widely known as the step rod seal. Combining a low-friction PTFE gliding element with an elastic O-ring energizer, it ensures exceptional static and dynamic sealing without stick-slip. Designed for precise positioning, it is the ideal choice for robotics, machine tools, and high-speed hydraulic cylinders. Supporting pressures up to 600 bar and fully compatible with ISO 7425-2 standards, the CS09-E offers superior mechanical efficiency and thermal resilience even in demanding air-in-oil conditions.
• No Stick-Slip: PTFE gliding part ensures smooth motion and prevents "crawling."
• ISO Standard Compatible: Dimensions according to ISO 7425-2 for easy global replacement.
• High Pressure Rating: Standard up to 400 bar, with special capabilities up to 600 bar.
• Precision Positioning: Minimal friction and low break-away force for exact control.
• Tandem System Ready: Perfect for use with double wipers (CW11) or secondary lip seals.
• Thermal Stability: Highly resistant to thermal damage and extreme temperature fluctuations.
