Solving Real Customer Problems Every Day

Often seals are the last thought to ever cross a customer’s mind, well until they begin to have trouble with the seal that is. Freudenberg Sealing Technologies works with some of the industry's best partners to solve real-world problems for end users every day. When a large Original Equipment Manufacturer (OEM) began to notice the performance of their current rod seal began to greatly decrease after only a few months they requested the support of Freudenberg’s preferred partner at Gallagher Fluid Seals for help.

The customer manufactures a wide range of materials testing equipment used by scientists, engineers, universities, and quality control managers. They specialize in products such as universal testing systems, automated testing systems, and dynamic and fatigue testing systems. The OEM customer‘s material testing system utilized a hydraulic cylinder to actuate test fixtures in a linear motion. The system is quite demanding as it is regularly run at high frequency for extended periods. Due to the constant motion, the rod seals were exhibiting signs of high wear causing downtime and other safety concerns.

Finding solutions for highly demanding applications

After reviewing the application Gallagher‘s solution engineers suggested a material change to Freudenberg Sealing Technologies high-performance polyurethane AU 30000. This specialized material is resistant to water, and other hydraulic fluids allowing it to be an ideal fit in the equipment. The AU 30000 compound was developed to handle major temperature and pressure fluctuations better than any other existing polyurethane on the market.

Thanks to the change to the industry-leading Freudenberg AU 30000 material, the customer‘s system saw the improved performance with increased accuracy by their measuring system all while greatly increasing the lifespan of the seal. The customer has also seen a great reduction in downtime thanks to the increased lifespan allowing them to focus on producing more products.

High-performance materials for operation in extreme conditions

Choosing the right seal is always critical to the performance, but when your equipment's application is highly demanding it becomes even more important. Freudenberg Sealing Technologies 94 AU 30000 is an outstanding choice when you need a seal to perform because it outperforms all other standard polyurethanes by a wide margin. In comparison tests under extreme conditions, seals made of the 94 AU 30000 material show no appreciable sign of wear while conventional seals fail prematurely. Even at 120 MPa, tear resistance the material performs about 30% better than the comparable polyurethanes.

The development of materials such as 94 AU 30000 polyurethane allows partners like Gallagher Fluid Seals to reliably find solutions to their customer's challenging sealing problems. Think Freudenberg Sealing Technologies 94 AU 30000 is the ideal solution to solve your sealing-related challenges?
