Laminar Rings

Product Details:

• 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.
