Sealing Rings for Aerospace Applications
SKF sealing rings are specified for a broad range of static and dynamic aerospace sealing ring applications, in turbine engines, actuators, auxiliary power units, environmental control units and high temperature valve applications for both military and commercial platforms. SKF designs and manufactures sealing rings that are applied as bearing damper rings, used in hydraulic systems, in valve and actuator assemblies, and other critical sealing applications. Decades of engineering, application and manufacturing expertise are behind every product produced, and results in SKF being a "go to" supplier for the most demanding applications.
A variety of materials are utilized depending on the application and range of service conditions. Patented joint configurations are available for those applications requiring the strictest leakage control and for blind assembly applications. Various coatings are also utilized and are specified based on the needs of the application.
