PTFE NBR hydraulic cylinder piston rod seals are high-performance sealing solutions designed for hydraulic systems. Combining a PTFE sealing ring with an NBR (Nitrile Rubber) elastomer, these seals offer excellent wear resistance, chemical compatibility, and elastic recovery. They are ideal for both dynamic and static applications, ensuring efficient sealing, preventing fluid leakage, and maintaining pressure in hydraulic cylinders under challenging conditions.
Key Features:
- Material Combination:
- PTFE Sealing Ring: Provides low friction, excellent wear resistance, and compatibility with a wide range of hydraulic fluids.
- NBR O-Ring: Offers elasticity, sealing reliability, and resistance to oils and greases.
- Low Friction and Smooth Operation:
- Reduces wear on the rod surface and ensures efficient operation of hydraulic systems.
- High Pressure and Temperature Resistance:
- Performs well in pressures up to 40 MPa and temperatures ranging from -30°C to +200°C (depending on material specifications).
- Excellent Fluid Compatibility:
- Suitable for use with mineral oils, synthetic oils, water-glycol fluids, and other hydraulic media.
- Durable and Reliable:
- The PTFE-NBR combination ensures a long service life even in harsh operating environments.
Applications:
- Hydraulic Cylinders:
- Provides effective sealing for pistons and rods in both industrial and mobile hydraulic systems.
- Construction Equipment:
- Widely used in excavators, cranes, loaders, and other heavy-duty machinery.
- Industrial Machinery:
- Suitable for presses, pumps, and other hydraulic equipment.
- Agricultural Machinery:
- Ensures reliable sealing in tractors, harvesters, and other farm equipment.
- Marine Applications:
- Performs well in hydraulic systems exposed to corrosive or wet environments.
