The elastic outer sheath of CFW is wrapped around a metal reinforcement ring and a spring supported sealing lip, setting a new standard for effective and reliable sealing.
Equipped with spring supported sealing lips and dust-proof lips, effectively preventing external pollution and ensuring optimal performance in harsh environments.
It performs well in a high thermal expansion shell, making it a perfect match for light metals and materials with high thermal performance.
Summary of Advantages:
- Good static sealing
- Reduced risk of fretting corrosion
- Effective protection against contaminants
- Up to 10 Bar pressure at moderate peripheral speed
Typically made from polyurethane, alternative materials can be provided upon request to suit your specific needs.
