FK3 Single Wound Sealing Rings

Single wound FK 3 Laminar Rings are used as grease seals for plain and roller bearing to provide protection against the ingress of dust and environmental moisture. The combined ASK or ISK ring sets optimize the sealing through the increased labyrinth effect.

Due to easier fitting in the grooves, the IS or ISK arrangement is preferred over the AS or ASK arrangement where this is possible. The ring carriers can be manufactured from steel, cast iron or plastic.
