Double-Turn laminar sealing rings combined

Product Description


Application “FK6 ASD” Outside clamping double rings (2 rings = 1 set) In contrast to the single wound laminar sealing rings “FK 3”, “FK6” double turn laminar sealing rings are double wound. They are used as grease seals for roller and plain bearings. They are also used as a protection seal in front of hermetically acting seal arrangements.

The “FK 6” double turn laminar sealing rings must meet special sealing requirements against grease leakage and against dust, dirt and splash water ingress. “FK 6” laminar rings provide a uniform radial tension and, in contrast to the “FK 3” laminar rings, they have no axial joint gap. The combined ring sets “FK6 ASKD” (additional sealing of the groove base diameter) optimize the sealing effect due to the increased labyrinth effect.

The “FK6 ASD” or “FK6 ASKD” assemblies are normally preferred over the “FK6 ISD” or “FK6 ISKD” due to their easier ring installation into the grooves of the ring carriers. Depending on the applications or the technical requirements, the ring carriers can be manufactured from steel, cast iron, light alloy or plastics.


Advantages of double turn laminar sealing rings

  1. The laminar sealing ring can adapt to the pressure and temperature of different working environments and has good sealing performance within the specified range, and the user can also adjust the sealing performance of the sealing ring appropriately according to the actual use situation.
  2. The laminar sealing ring has a stable friction coefficient. The friction between the device protected by the laminar sealing ring and the moving parts should be kept as small as possible and kept within the specified range, which is critical to prolonging the service life of the equipment and preventing the equipment from being damaged.
  3. The laminar sealing ring has good corrosion resistance. Generally, in the use environment of a laminar sealing ring, it is difficult to avoid some chemical reactions between gas and liquid. The good corrosion resistance of the laminar sealing ring enables it to maintain a long service life and delay the speed of aging.
  4. Strong wear resistance. Under long-term work and high-intensity pressure, the friction consumption is very small, and it has good working quality.
  5. The laminar sealing ring has a simple structure, which is convenient in use, maintenance, and replacement, which also improves its service life to a certain extent.
