Freudenberg Offers Sealing Solution Expertise for HAGC Cylinders

Company highlights new solutions, materials at 2019 AISTech

Plymouth, Mich. (USA), May 6, 2019. In the steel industry, the hydraulic automatic gauge control (HAGC) cylinders used in mills pose a big challenge to sealing systems, which need to handle high extrusion resistance and maintain low friction at the same time. Freudenberg Sealing Technologies will exhibit its range of seal systems and materials for HAGC applications and more at the 2019 AISTech Conference and Exposition – the steel industry’s premier technology event – at the David L. Lawrence Convention Center in Pittsburgh, May 6 to 9.

“A sealing system in a steel mill often must withstand nonstop, 24/7 operation of the facility’s equipment, a task that only becomes more intense on a HAGC cylinder, which has a stroke of less than 2mm during operation at a frequency of up to 15 cycles per second,” said Robin Moeller, Global Business Development Manager Heavy Industry, Freudenberg. “We have addressed challenges such as these with dedicated research to identify the right materials to help our customers meet performance requirements in countless production environments.”

For maximum machine loads, Freudenberg offers its compact Omegat seal, which comes combined with a PT2 wiper. Both are made of polytetrafluoroethylene (PTFE). The PTFE system is ideal for maximum performance in a 24/7 operation and stands up to temperature increases and loss of lubrication, providing optimal safety and protection against failures.

For applications where operation is intermittent and the system has opportunities for cool-down, Freudenberg offers polyurethane (PU) sealing solutions, including components featuring its new PU 21430 material, which offers impressive abrasion and extrusion resistance, is easy to install and is an ideal solution for medium machine loads.

“With more than 170 years of sealing expertise, Freudenberg prides itself on providing the best solution for every specific requirement that manufacturers might encounter,” said Moeller.
