Understanding Polyurethane Piston Seals
What Are Polyurethane Piston Seals?
Polyurethane Piston Seals, PU piston seals, or urethane piston seals are advanced sealing components used in hydraulic cylinders and pneumatic systems. They offer a unique combination of strength, flexibility, and wear resistance that outperforms traditional seal materials like rubber or nitrile.
How Polyurethane Piston Seals Work
These seals create a dynamic barrier between the piston and cylinder wall. As pressure increases, the seal lip activates, pressing more firmly against the cylinder surface to prevent fluid bypass and maintain system efficiency.
Benefits and Key Features
- High abrasion resistance for extended seal life
- Excellent compression set resistance for maintained sealing force
- Superior resilience and tear strength
- Low friction for improved system efficiency
- Compatibility with a wide range of hydraulic fluids
Types of Polyurethane Piston Seals
U-cup Seals (U-Rings)
- Versatile design suitable for various applications
- Available in single and double-lip configurations
- Excellent bidirectional sealing capabilities
Lip Seals
- Optimized for unidirectional sealing
- Lower friction compared to U-cup seals
- Ideal for specific application requirements
Slipper Seals
- Designed for high-speed, low-friction applications
- Excellent wear resistance and long service life
- Suitable for both hydraulic and pneumatic systems
Ring Type Seals
- Includes O-rings and backup rings
- Provides additional support and extrusion resistance
- Often used in combination with other seal types
Comparison of Seal Types
| Seal Type | Pressure Rating | Friction | Bidirectional Sealing |
|-----------|-----------------|----------|------------------------|
| U-cup | High | Medium | Excellent |
| Lip | Medium | Low | Good (unidirectional) |
| Slipper | Medium-High | Very Low | Good |
| Ring Type | High | Low | Excellent (with backups)|
