Longer Lifetimes, Lower Costs: The 94 AU 30000 Material Advantage

SPONSORED BY:

Seals are the workhorses of hydraulic systems, and the demands placed on seals can be extreme in today’s increasingly rugged industrial applications. Challenges such as higher temperatures, fluctuating pressures, aggressive media, difficult terrain, longer working hours, and fewer maintenance intervals can lead to seal extrusions and leakage. The result is system failure and downtime.

Advanced components are required, but they are only as good as the materials from which they are made. A new material, 94 AU 30000, was developed to address these emerging fluid power requirements. More resistant to water and synthetic hydraulic fluids, 94 AU 30000 withstands major temperature and pressure fluctuations better than other existing polyurethane materials. The material accommodates double extrusion gaps, offers excellent performance in heat and cold, and can be used in mineral hydraulic fluids at temperatures ranging from -31°F (-35°C) up to 248°F (120°C). Mobile machinery customers, in particular, can benefit from these characteristics.

This Tech Talk examines 94 AU 30000 as a material innovation that is powering development of advanced seals, gaskets, and other components that meet and exceed industry expectations. It also is one of the primary materials used by Freudenberg Xpress®, the company’s service for manufacturing replacement parts, prototypes, and small production runs of seals.
