Taming the toughest environments

Sealing solutions for the global construction industry

Construction and mining machines operate in the most diverse, challenging, and demanding environments around. Freudenberg Sealing Technology offers industry-leading solutions.


Cassette axle seals

FST Kassettendichtungen Cassette Seals

For example Cassette axle seals, that resist mud, water and other invasive media, along with fluid power seals made of elastomers, urethanes, and PTFE for sealing high-pressure hydraulic systems. Our experience ensures a reliable solution for any sealing need – as does our ability to work as an extension of the customer’s engineering team. Downtime equals lost profit. Freudenberg Sealing Technologies’ innovative line of polyurethane hydraulic cylinder seals ensures thousands of hours of uptime and high reliability.

Operator safety and comfort are the focus for construction machines. Rough terrain not only causes driver discomfort. It can often make equipment operation dangerous as well. Freudenberg’s accumulator suspension systems stabilize the cab, maximizing operator comfort while minimizing the effect of the terrain in all types of equipment.
