labyrinth sealing rings

FK 3 Single laminar 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.

FK 5 Single and/or double laminar sealing rings 

Single and double wound rings are manufactured from special materials and use special processes. FK 5 and FK 5-HFL rings are used when applications require extreme temperature and corrosion resistant properties. Single and double wound laminar sealing rings are used for both rotating and static applications. 

FK 5 Sealing Rings 

FK 5 sealing rings are designed to handle applications where high temperature and corrosion resistance is required. This makes an excellent sealing solution for primary metals operations. For many years major manufacturers of continuous casting lines have been using double wound Fey Laminar Sealing rings to seal their bearings.

FK 5 - HFL Sealing Rings 

FEY created their FK 5-HFL laminar sealing ring series to handle the demands of applications where gases need to be sealed under pressure and extremely high temperatures. Features of this series come from years of design experience. 

FK 6 Double laminar sealing rings 

FK 6 laminar rings are double wound. They serve as a grease seal for plain and roller bearings and are also used as a protective seal in front of radial lip seals. Higher sealing performance is achieved by the FK 6 laminar rings when exuding grease. They also provide better protection against dust, dirt and splash water. FK 6 laminar rings are outstanding for their high retention force and have no joint gap. The combined ASKD or ISKD ring sets optimize the sealing as a result of the increased labyrinth effect. 

Due to easier fitting in the grooves the ISD or ISKD arrangement is preferred over the ASD or ASKD arrangement where this is possible. The ring carriers can be manufactured from steel, cast iron or plastic.
