FEY Labyrinth Sealing Rings
Protect components in dirty and abrasive environments up to 700oC
Application "FK7 DSW" Double retaining ring shaft The double wound laminar retaining rings "FK7 DSW" for shafts are a valuable addition to the single wound laminar retaining rings "FK7 ESW". The application range for the double wound laminar retaining rings "FK7 DSW" for shafts includes applications where the components need to be axially retained, e.g. for transmission systems, construction equipment and agriculture machinery, for fastening elements in the automotive industry and mechanical engineering, in the roller and plain bearing industry, for ship and aircraft building, winches, pulleys, etc. Advantages of the double wound laminar retaining rings:
Axial Stress
Shearing tests under operating conditions must be performed to determine the axial shearing capacity of the retaining rings. The secure position of the retaining rings in the groove cannot be guaranteed if the surrounding components thrust uncontrollable against the laminar rings during operation (coupling effect) or if the components vibrate extremely.
Ordering Information The ring diameter information must match bore dimensions ‘D1’ for all enquiries and/or orders.
Run and Installation Tests Run and installation tests under operating conditions must be performed in each case before standard production of FEY laminar rings can begin to determine whether the desired sealing effects can be achieved.
