Application “FK3 IS” Inside clamping single rings (3 rings = 1 set)
Single wound laminar sealing rings “FK3 IS” are used as a grease seal for roller and plain bearings and they protect, if greased, against dust entry and ambient moisture. The combined ring sets “FK3 ISK” (additional sealing of the groove base diameter) optimize the sealing effect due to the increased labyrinth effect.
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.
