General Information
FK7 DSB DOUBLE WOUND 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”
Permissible circumferential speed (in m/s)
Axial and/or radial play
