Cased Spring Seal Canted Coil

ECLIPSE ECSC – CASED CANTED COIL SPRING ENERGIZED SEAL

Cased Spring Seals are the best option for extreme rotary service. In these designs, a metal case is constructed around the outside of a spring seal, which in turn gets press-fit into the hardware bore. A metal-to-metal press-fit ensures a tight seal as well as a highly effective anti-rotation mechanism. Because these seals are installed into open bores, they lend themselves to rotary applications such as gearboxes and power transmission systems. They can also be utilized as rod end scrapers, where exclusion of aggressive media is desired.
