Fey FK3 SINGLE WOUND LABYRINTH SEALING RINGS
Single wound FK 3 labyrinth sealing 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 optimise the sealing through the increased labyrinth effect.
Due to easier fitting in the grooves, IS or ISK is preferred over the AS or ASK where this is possible. The ring carriers can be manufactured from steel, cast iron or plastic.
