Safety Is the Key

Sealing Solutions for the Mining Industry

Safety is the highest priority when it comes to working underground. This puts the greatest possible quality demands on mining machinery, products and service providers. At the same time, operating efficiency plays a key role in this industry as well. So it is essential to bring three factors into harmony: cost minimization and the simultaneous maximization of productivity and safety. Freudenberg Sealing Technologies provides seals and sealing systems that live up to these standards.

Special Sealing Element Design

Sand, mud, water and fallen rocks are just a few of the challenges facing seals in mining operations. In addition, there are peak pressures of up to 250 MPa, which require a special sealing element design. High extrusion resistance is especially in demand. Parts of the seal or even the seal itself must not be forced into the gap between the design’s moving and fixed elements. That would greatly reduce the seal’s operating life.

In close cooperation with customers, installation proposals are developed with all the components of the seal system. They contain all the seal-relevant dimensions and tolerances, the maximum guide stresses and the resulting individual clearances. Whether in the customer's design department or during service on-site, these certified installation drawings save time and money while ensuring design safety.
