Single wound FK3 Laminar Rings are used as grease seals for plain and roller bearings 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 groves the IS or ISK arrangement is prefered over the AS or ASK arrangement where this is possible. The ring carriers can be manufactured from steel, cast iron or plastic. View Chart.

Double and single wound rings for sealing axial compensators in exhaust gas systems for internal combustion engines, manifold and sheet metal pipe connections.

APPLICATIONS: FK5 and FK6 compared with the single wound FK3 Laminar Rings, FK5 and FK 6 Laminar Rings are double wound. They serve as a grease seal for plain roller bearings and are also used as a protective seal in front of rubber lip seals. Higher sealing performance is achieved by the FK5 and FK6 Laminar Rings in respect of excluding grease and also provide protection against dust, dirt and splash water. FK5 and FK6 Laminar Rings are outstanding for thier high retension force and have no joint gap when compared with FK3 Laminar Rings. The combined ASD or ISKD ring sets optimise the sealing as a result of the increased labyrinth effect. Due to easier fitting in the grooves the ISD or ISKD arrangement is prefered over the ASD or ASKD arrangement where this is possible. The ring carriers can be manufactured from steel, cast iron or plastic. View Chart
