FK7 laminar retaining rings
Single and double wound laminar retaining rings
FK7 are single or double wound steel retaining rings. They are available in both internally and externally clamping versions. FK7 retaining rings are used for axial locking and are used in transmission systems, agricultural vehicles and the locking of parts in the automotive industry.
FK7 retaining rings are available in various lock designs with a straight lock, slanted lock or with a recess.
FK7 ESB
The type FK7 ESB are single-wound external retaining rings. These retaining rings are used for axial locking.
FK7 ESW
The type FK7 ESW are single-wound internal retaining rings for shafts. These retaining rings are used for axial locking.
FK7 DSB
The type FK7 DSB are double-wound external retaining rings. These retaining rings are used for axial locking.
Advantages of the double-wound versions are:
- Due to the double winding, the contact with the full circumference of the groove is guaranteed
- More stable due to the uniform dynamic weight during rotation
- Possibility of a higher axial load than with single-wound versions
FK7 DSW
The type FK7 DSW are double-wound internal retaining rings for shafts.
Advantages of the double-wound versions are:
- Due to the double winding, the contact with the full circumference of the groove is guaranteed
- More stable due to the uniform dynamic weight during rotation
- Possibility of a higher axial load than with single-wound versions
FK7 DMS
The type FK7 DMS are double-wound internal retaining rings for shafts with centrifugal force protection.
Advantages of the double-wound versions are:
- Due to the double winding, the contact with the full circumference of the groove is guaranteed
- More stable due to the uniform dynamic weight during rotation
- Possibility of a higher axial load than with single-wound versions
