FEY Labyrinth Sealing Rings:
- FK 3 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.
 - FK 5 Single and/or double laminar sealing rings – Single and double wound rings are manufactured from special materials and use special processes.
- FK 6 Double laminar sealing rings – 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.Â
Fey laminar rings are sealing elements for both rotating and static applications. These rings use a low-contact labyrinth design with small gap widths, making them effective for grease sealing and preventing the entry of fluids, dirt, dust, and other contaminants. Their design also reduces friction, heat, and wear, making them suitable for high-speed and temperature-sensitive applications.
For static applications, such as axial compensators in exhaust manifold systems, exhaust gas recirculation systems, and power units with temperatures up to 700°C, Fey laminar rings are made from chrome-nickel materials. These materials retain their spring properties and heat resistance even at high temperatures, ensuring reliability.
Fey laminar rings come in single wound (FK3) and double wound (FK6/FK5/FK5-HFL) versions. Single wound rings have a joint gap (AS and IS), while double wound versions do not (ASD and ISD). The choice of ring type depends on the operating environment, movement patterns, and specific leakage requirements.
Fey laminar rings can be combined in a groove using both outspringing and inspringing rings, depending on the application. Additional coverage at the groove base enhances the labyrinth effect, optimising sealing. However, such combinations are not suitable for every task. Axial movement of the ring sets due to bearing play must be avoided, as it can cause friction between the rings and groove flanks, leading to premature wear.
