FK 7 DSB Double laminar retaining rings for bores

Application “FK7 DSB” Double retaining ring bore

The double wound laminar retaining rings “FK7 DSB” for bores are a valuable addition to the single wound laminar retaining rings “FK7 ESB”.
The application range for the double wound laminar retaining rings “FK7 DSB” for bores 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:

  • Roundness of the closed winding over a range of 360° guarantees fixed contact to the groove base and full circumferential tightness
  • Uniform dynamic weight during rotation
  • Higher axial resilience as compared to the single wound laminar retaining rings “FK7 ESB”

Axial stress 3):

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.

Order information 4):

The ring diameter information must match the housing or bore diameter dimensions “D1″ for all inquiries and/or orders.

Run and installation tests:

Run and installation tests under operating conditions must be performed in each case before standard production of our laminar rings can begin to determine whether the desired sealing effects can be achieved.
