- Double-acting scraper with two O-rings functioned as elastic energizer to preload the PTFE compound ring
- The double O-ring design can improve rod sealing performance under short-stroke and high-frequency motion
- Common application includes fork-lift trucks, injection molding machines, compression molding press, and agriculture equipment
- A small bore hole for relieving pressure is recommended for some combined seals that lack of sufficient pump-back capability
Application Range
- Temperature: -40℃ ~ 200℃
- Speed: ≦ 5 m/s
- Standard Material: Bronze filled PTFE
- (Note: Other materials are available for specified conditions)
Common Applications
