The SPGW piston seal ring is a robust, high-performance sealing solution designed for hydraulic cylinders. It combines a multi-component design, typically featuring a main sealing ring made of PTFE or polyurethane (PU), an elastomer O-ring for elasticity, and back-up rings for high-pressure stability. The SPGW piston seal offers excellent sealing efficiency, wear resistance, and durability in demanding applications, making it ideal for heavy-duty industrial and mobile machinery.
Key Features:
- Multi-Component Design:
- Sealing Ring (PTFE or PU): Provides low friction, excellent wear resistance, and chemical compatibility.
- Elastomer O-Ring: Enhances elasticity and sealing effectiveness.
- Back-Up Rings: Ensures stability under high-pressure conditions.
- High Pressure and Temperature Resistance:
- Suitable for pressures up to 40 MPa and temperatures ranging from -30°C to +200°C (depending on material selection).
- Low Friction:
- Ensures smooth operation, reducing wear on the sealing surfaces and improving system efficiency.
- Wide Fluid Compatibility:
- Compatible with various hydraulic fluids, including mineral oils, synthetic oils, and water-glycol fluids.
- Long Service Life:
- Combines wear-resistant materials with a stable design to reduce maintenance needs and increase reliability.
Applications:
- Hydraulic Cylinders:
- Designed to seal the piston interface, ensuring efficient operation and pressure retention.
- Construction Equipment:
- Used in excavators, loaders, cranes, and other heavy-duty machinery.
- Industrial Machinery:
- Suitable for hydraulic presses, pumps, and other high-pressure systems.
- Agricultural Equipment:
- Ensures reliable sealing in tractors, harvesters, and other machinery.
- Marine and Offshore Equipment:
- Provides effective sealing in hydraulic systems exposed to harsh environments.
