- Adaptable to special working environments by adjusting axial preload (using slots or ring head screws).
- Stable design makes it resistant to high-pressure peaks.
- Less sensitive to medium contamination and minor sliding surface damage compared to single seals.
- Multiple sealing lips and a broad contact area ensure excellent sealing efficiency.
- Seals can be cut for easy installation, eliminating the need to fully disassemble the cylinder during maintenance or repairs.
Rod seals are used in hydraulic cylinders for fluid sealing. They are external to the cylinder head and seal against the cylinder’s rod, preventing leakage of fluid from within the cylinder to the outside.
Yimai Sealing Solutions offers a wide range of hydraulic rod seals that provide the ultimate in protection from ingress of media. This includes O-Ring energized Polytetrafluoroethylene (PTFE) seals, polyurethane (PU) U-Cups, and many more. Our proprietary rod seal designs meet users’ requirements for low friction, compact form and simple installation.
A hydraulic rod seal is usually manufactured in our PTFE based material or polyurethane. Specially engineered for fluid power applications, these compounds provide exceptional resistance to wear and outstanding extrusion properties. Options are available that are compatible with virtually all media, they demonstrate unrivalled temperature performance.
