About Fey

In 1946, the "FK2 AS" was the first laminar ring to be developed and produced. This single-wound laminar ring was used in the pistons of internal combustion engines in order to re-establish the seal of oval and worn cylinders. The laminar rings were made from spring steel and are also available in stainless steel and alloys that will withstand high temperatures.

The first use of Fey rings was successful for many years, but it was not able to secure the economic future of Fey.

One important precondition for the further development of the laminar ring seals was the development of a cost-effective production method. The rings are thermally tensioned in an oval form. Following their installation, externally tensioned rings in cylinders and internally tensioned rings on shafts, they are round and provide the best possible seal.

Through these developments, and the successful effect of butt and labyrinth seals, Fey was in a position to offer industry a whole range of sealing solutions. This led to more enquiries and requirements, which in turn resulted in a range of seals with diameters ranging from 15 to 1,300 mm. In the meantime, the range had expanded to approximately 16,800 types with different diameters, thickness and width and materials.

Satisfied users of Fey laminar rings include manufacturers of roller and slide bearings, exhaust couplings, rolling stock axle bearings, continuous casting machines and gearboxes.
