When are static seals used in hydraulics?
By Josh Cosford, Contributing Editor Static seals are used in hydraulic applications where two mating surfaces or edges require positive sealing. A static seal, by definition, is one that remains stationary and subjected to no movement and its related friction. A static seal may be exposed to hydraulic pressure on both sides or be exposed to … [Read more...] about When are static seals used in hydraulics?
Trelleborg’s tensioner cylinder seals exceed 20-year lifecycle rating
Seals used in offshore rig tensioner cylinders must meet the same rigorous lifecycles as the cylinders themselves. Because offshore environments are harsh and installation and maintenance can be difficult, tensioner cylinders must have a 20-year life. That was why, more than 20 years ago, Trelleborg Sealing Solutions conducted research, determining … [Read more...] about Trelleborg’s tensioner cylinder seals exceed 20-year lifecycle rating
