General Information
FK7 ESW SINGLE WOUND LAMINAR RETAINING RINGS FOR SHAFTS
Application “FK7 ESB” Single retaining ring bore
The application range for the single wound laminar retaining rings “FK7 ESB” 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.
Assembly/disassembly features are special options for single wound laminar retaining rings.
Permissible circumferential speed (in m/s)   Â
Axial and/or radial play
FK7Â DMS ring
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.
