FK 6 - ISD
FK 6 ISD Double laminar sealing rings
Application "FK6 ISD" Inside clamping double rings (2 rings = 1 set)
Double wound laminar sealing rings "FK6 ISD" are used as a grease seal for roller and plain bearings and they protect, if greased, against grease leakage as well as against dust, dirt and splash water ingress, especially if the sealing requirements are high. Double wound laminar rings provide a uniform radial tension and, in contrast to the single wound "FK3" laminar rings, they have no axial joint gap. The combined ring sets "FK6 ISKD" (additional sealing of the groove base diameter) optimize the sealing effect due to the increased labyrinth effect.
The "FK6 ASD" or "FK6 ASKD" assemblies are normally preferred over the "FK6 ISD" or "FK6 ISKD" assemblies due to their easier installation into the grooves. Depending on the applications or the technical requirements, the ring carriers can be manufactured from steel, cast iron, light alloy or plastics.
Axial and/or radial play 3) :
The groove width "A" must be widened by twice the play if play occurs in the area of the rings. The groove base diameter "D2" must be increased by the radial play if radial play occurs. Damage to the rings and the surrounding components occurs if this is not adhered to. It is recommended to use the full groove width tolerances, especially in the case of thermal expansion.

Order information 4) :
The ring diameter information must match shaft diameter dimensions "D1" for all inquiries and/or orders. The rings can be ordered individually or in sets (1 set = 2 ISD rings).
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.
