# **SKF Static Seals & O-Rings: Reliable Sealing Solutions for Demanding Industrial Applications**

In industrial machinery, automotive systems, and precision equipment, effective sealing is critical to preventing leaks, contamination, and premature component failure. SKF, a global leader in sealing technology, offers a comprehensive range of **static seals and O-rings** designed to deliver superior performance in even the most demanding environments. Engineered with precision materials and advanced manufacturing techniques, SKF static seals ensure long-lasting reliability, reduced maintenance costs, and enhanced operational efficiency.

## **Technical Features & Material Excellence**

SKF static seals and O-rings are manufactured using high-quality elastomers and engineered polymers, including:

– **NBR (Nitrile Rubber):** Excellent resistance to oils, fuels, and hydraulic fluids, making them ideal for automotive and industrial hydraulic systems.
– **FKM (Fluoroelastomer/Viton®):** Superior chemical and heat resistance, suitable for high-temperature applications in chemical processing and aerospace.
– **EPDM (Ethylene Propylene Diene Monomer):** Outstanding resistance to water, steam, and weathering, commonly used in food processing and HVAC systems.
– **Silicone & PTFE:** Used in extreme temperature ranges and applications requiring low friction or high purity, such as medical and semiconductor equipment.

SKF seals are precision-molded to ensure consistent dimensions and optimal compression set resistance, maintaining a secure seal over extended periods.

## **Performance Advantages**

– **Leak Prevention:** Precision-engineered sealing surfaces minimize fluid or gas leakage, even under high-pressure conditions.
– **Long Service Life:** High-grade materials resist degradation from chemicals, temperature fluctuations, and mechanical stress.
– **Reduced Friction & Wear:** Optimized seal geometry ensures minimal drag, enhancing energy efficiency in dynamic systems.
– **Wide Temperature & Pressure Range:** Suitable for applications ranging from cryogenic conditions to +300°C (depending on material).
– **Easy Installation:** Standardized sizes and robust design simplify assembly and replacement.

## **Typical Applications**

SKF static seals and O-rings are widely used across industries, including:

– **Industrial Machinery:** Hydraulic cylinders, pumps, compressors, and valve sealing in heavy equipment.
– **Automotive Systems:** Engine gaskets, fuel systems, transmission seals, and brake components.
– **Precision Equipment:** Semiconductor manufacturing, medical devices, and laboratory instruments requiring contamination-free sealing.
– **Energy & Chemical Processing:** Seals for pipelines, reactors, and offshore equipment exposed to aggressive media.

By choosing SKF static seals and O-rings, engineers and maintenance professionals benefit from a trusted sealing solution that enhances equipment durability, reduces downtime, and improves overall system performance. Whether in harsh industrial environments or precision applications, SKF delivers sealing reliability backed by decades of engineering expertise.
