Product description

FK 3 ISK - Single laminar sealing rings combined for shafts

Application “FK3 ISK” Inside clamping combined single rings (5 rings = 1 set)

Single wound laminar sealing rings “FK3 ISK” are used as a grease seal for roller and plain bearings and they protect, if greased, against dust entry and ambient moisture. Due to the increased labyrinth effect, the sealing effect is optimized by the additional sealing of the groove base diameter.

The “FK3 AS” or “FK3 ASK” assemblies are normally preferred over the “FK3 IS” or “FK3 ISK” 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:

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 ingreased 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.

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.
