PU Hydraulic Seals are critical components designed to contain hydraulic fluid and maintain pressure in high-performance hydraulic systems. These seals ensure leak-free operation by preventing fluid leakage between components such as pistons, rods, and cylinder bores, even under extreme pressures, temperatures, and dynamic movements.
Key Features:
- High-Pressure Resistance: Capable of withstanding pressures in static and dynamic applications.
- Superior Wear Resistance: Formulated from high-performance polyurethane (PU) elastomers for long service life.
- Low Friction & High Efficiency: Optimized lip designs minimize friction and prevent stick-slip, improving system responsiveness and energy efficiency.
- Precision Fit: Manufactured to tight tolerances for compatibility with various ISO, DIN, and custom cylinder dimensions.
Types of Hydraulic Seals Offered:
- Rod Seals: Prevent leakage from inside the cylinder to the outside environment.
- Piston Seals: Ensure fluid containment and pressure sealing within the cylinder bore.
- Wiper Seals (Scrapers): Remove contaminants from piston rods before retraction.
- Wear Rings (Guide Rings): Prevent metal-to-metal contact and support lateral loads.
- Buffer Seals: Absorb pressure shocks and protect primary rod seals in high-speed systems.
- O-Rings & Backup Rings: Provide secondary static sealing support.
Applications:
- Hydraulic cylinders and presses
- Injection molding machinery
- Construction and mining equipment
- Material handling systems
- Marine hydraulics
- Industrial automation
