Fey laminar rings used as sealing elements for rotating and static sealing applications:

Fey laminar rings combine a low contact multiple labyrinth with very little gap width and are especially effective for grease sealings and for the exclusion of fluid media, dirt and dust entry as well as other contaminations.

In addition to their outstanding sealing characteristics for rotating components, the low contact laminar rings with low friction produce a significant reduction of internal heat and wear, which qualifies these sealing elements for high speed applications and applications in temperature and/or friction sensitive installations.

For static sealing applications such as axial compensators at screwed exhaust manifold systems for internal combustion engines, exhaust gas recirculation systems and power units with operating temperatures of up to +700°C, Fey laminar rings will be manufactured from chrome nickel materials, which are spring and heat resistant in the sealing area even at high temperatures.

Design types include single wound (FK3) and double wound (FK6/FK5/FK5-HFL) laminar rings:

Fey laminar rings are offered as single wound laminar rings (AS and IS) with joint gap and as double wound laminar rings (ASD and ISD) without joint gap. The use of the different laminar ring geometries and the design of the installation technology depend on the operating conditions, the motion sequence of the components to be sealed and on the leakage requirements of the customer. In addition to single outspringing or single inspringing ring sets, Fey laminar rings can also be combined as a ring set within a groove: outspringing rings with inspringing rings and vice versa. The additional coverage of the groove base plays within the bore of the housing or at the groove base of the shaft optimize the labyrinth effect and therefore the sealing effect. However, we must point out that these combinations cannot be recommended for all sealing tasks.

One thing which must be avoided at all costs is that the laminar ring seal sets are moved axially by the movement of the groove, which may result from the axial play in the bearings. Depending on the frequency involved, friction would be generated between the ring and the groove flanks which may lead to premature wear of the rings and adjacent components.

Questionnaire:

This web site cannot show all potential applications for the laminar rings. This is why we refer to the questionnaire. The answers may put us into the position to address your sealing issues and to proposes appropriate recommendations.

Run and installation tests:

Run and installation tests under operating conditions must be performed in each case before standard production can begin to determine, whether the desired sealing effects for laminar sealing rings or the retaining effects for laminar retaining rings can be achieved. We recommend to contact our technical office for clarification.
