Seals Product Introduction
**Introduction to SKF Static Seals and Back-Up Rings: Engineered for Reliability and Performance**
In demanding industrial environments, preventing leaks and ensuring long-term sealing integrity are critical to maintaining equipment efficiency and reducing downtime. SKF, a global leader in sealing solutions, offers a comprehensive range of **static seals and back-up rings** designed to deliver exceptional performance in high-pressure, high-temperature, and chemically aggressive applications. These precision-engineered components are trusted across industries—from heavy machinery and automotive systems to hydraulic equipment and precision instruments—where reliability and durability are non-negotiable.
### **Technical Features and Design Excellence**
SKF static seals and back-up rings are manufactured using advanced materials and cutting-edge engineering to meet the toughest operational challenges. Key features include:
– **High-Performance Materials**: SKF utilizes premium elastomers (such as FKM, NBR, and EPDM) and thermoplastics tailored for specific conditions, ensuring resistance to extreme temperatures, hydraulic fluids, and corrosive media.
– **Optimized Geometry**: Precision-molded profiles ensure uniform compression and effective sealing, even in uneven or dynamic mating surfaces.
– **Back-Up Ring Support**: Reinforcing back-up rings prevent extrusion and deformation of primary seals under high-pressure conditions, extending service life.
– **Customization Options**: Available in a variety of sizes, hardness levels, and cross-sections to fit unique application requirements.
### **Performance Advantages**
SKF’s static seals and back-up rings are designed to outperform conventional solutions by addressing common failure modes such as extrusion, blow-out, and chemical degradation. Benefits include:
– **Enhanced Pressure Resistance**: Back-up rings stabilize primary seals, enabling reliable performance in systems exceeding 5,000 psi (350 bar).
– **Extended Service Intervals**: Reduced wear and leakage minimize maintenance needs, lowering total cost of ownership.
– **Broad Compatibility**: Suitable for use with oils, greases, water, and aggressive chemicals, making them ideal for diverse industrial and automotive applications.
– **Temperature Resilience**: Operates reliably in a range from -40°C to +200°C (-40°F to +392°F), depending on material selection.
### **Typical Applications**
SKF static seals and back-up rings are widely used in:
– **Hydraulic Systems**: Cylinders, pumps, and valves in construction, mining, and agricultural machinery.
– **Automotive Components**: Transmission systems, fuel injectors, and brake assemblies where high-pressure sealing is essential.
– **Industrial Machinery**: Presses, compressors, and turbines requiring robust sealing under cyclic loads.
– **Precision Equipment**: Aerospace and semiconductor manufacturing tools demanding contamination-free operation.
By combining material expertise with precision engineering, SKF’s static seals and back-up rings provide a dependable solution to sealing challenges—ensuring leak-free operation, reducing energy losses, and enhancing the longevity of critical equipment. For industries where failure is not an option, SKF delivers sealing solutions that stand the test of time.
