Fey Lamellenringe GmbH & Co. KG
More than 75 years of experience
Those who have followed the development of Fey laminar rings since 1946 will remember that laminar rings were first produced in Germany in a single wound version. The "FK2 AS" was used to equip previously used pistons in internal combustion engines to reestablish the sealing or the compression in oval and "worn out" cylinders. These laminar rings were made from spring band steel or flat wire, including stainless steel and high-temperature alloys.
Development of Fey lamellar rings
A significant condition for the further development of the Fey laminar ring sealings was the development of a cost effective manufacturing process, so that the rings could be manufactured individually in an oval format through thermal treatment, becoming round when installed in their working conditions as out-springing rings into bores or as in-springing rings on shafts by providing the highest possible gap sealing. Using these arguments and the positive sealing effects of gap and labyrinth sealings, Fey was in a position to address the sealing problems of the industry and this resulted in increasing inquiries and requirements that led to a sealing program with a diameter range from 15 mm to 1,300 mm. In the meantime, Fey's manufacturing program consists of app. 16,800 ring types with different ring diameters, ring cross sections and different ring materials.
Successful users of Fey laminar rings include manufacturers of roller and plain bearings, exhaust pipes of internal combustion engines, axle bearings of rolling stock, continuous casting plants, transmission systems, power units and many more.
