5 Saving Mill Operators Millions of Dollars Many steel and aluminum mill operators don t realize the extent to which they can dramatically improve productivity through better seal performance. Using advanced engineering techniques such as finite element analysis, System Seals develops customized products for OEMs and mill operators that substantially extend the time between scheduled maintenance. In some cases, products designed by System Seals allow mills to skip an entire outage and save millions of dollars in the process. Nearly a decade ago, System Seals transformed the reliability of steel mill hydraulics industry wide when it first applied specialty Hydrogenated Nitrile Compounds as a replacement for the previous Fluoroelastomer compounds such as VITON. The breakthrough came from a single customer, who realized that fire-resistant fluids were degrading a competitor s seals. This one request inspired System Seals engineers to reexamine the material selection for all seal materials used in steel mill hydraulics. After extensive laboratory testing with a variety of new materials, System Seals focused in on an innovative design and verified the results through independent labs. In the end, a new series of specialty HN compounds have become the undisputed industry standard. Today, System Seals continues to work with the largest OEMs and mills around the world improving designs and materials. This includes proprietary PTFE blends that consistently outperform competitor seals in side-by-side testing. The results offer longer life, greater reliability and the option to extend time between outages.

This shared process ensures that every OEM product is the best in the world and delivered as quickly and efficiency as possible anywhere in the world. olling mills with Hydraulic Automatic Gauge Control systems (HAGC) appreciate the importance of precision down to the hundredth of a millimeter. The challenge in designing seals for HAGCs is striking a precise balance between performance and control. These systems require heavy-duty seals robust enough to resist extrusion, wear and prevent damaging the running surface. ut they must also minimize friction to remain extremely responsive and dynamic. It s a difficult equilibrium, but finding the sweet spot between precision and reliability is what sets System Seals apart. This is why the world s leading HAGC manufacturers and steel mills increasingly turn to System Seals to improve equipment performance and reliability. It s an industry focus that has distinguished the company through decades of experience inside mills and a relentless drive toward engineering excellence. System Seals approaches each piece of equipment by developing a full body diagram of the HAGC system. Engineers examine groove dimensions, tolerances, fluids, clearances, guidance within the cylinder and the guide bushings, which play an essential role governing side loads and preventing metal-to-metal contact inside the cylinder. System Seals tests and refines all new designs in its in-house research-anddevelopment facility. And to avoid expensive, time-consuming repairs, System Seals can perform a failure analysis for a better understanding of the equipment and make recommendations for preventive maintenance. System Seals works closely with HAGC manufacturers to customize seals for optimum performance. In some cases, engineers suggest ways to decrease the size of hydraulic pistons for a more compact design that reduces build materials, costs and manufacturing time. And System Seals shares its customers sense of urgency to always develop the best solution as quickly as possible. The 317 Mill-Duty, Double-Acting Wiper systemseals.com

This guide band is substantially stronger than olyamide-based materials and offers considerably lower water absorption. This new composite provides more accurate piston and rod guidance inside the cylinder under widely varying load conditions. educed bushing deformation allows the seals and wipers to perform at maximum efficiency, while minimizing the risk of scoring and abrasion. The 845 is split at a 45 angle, and the 890 is cut at 90 angle. PODUCT ENEFITS Very accurate and precise guidance of the cylinder components Withstands very high side loads during operation Maximizes efficiency of the dynamic seals Wide temperature range APPICATIONS The 845/890 Series Guide and is the ideal solutions where high side loads and deflections are present.
