Laminar Sealing Rings

Laminar Sealing Rings are non-contacting (labyrinth) seals,

ranging from 15 - 1300mm in diameter (0.6 - 51 inches) and are produced

as single and double wound versions; several grades of spring-steel are

available (including stainless steel up to Æ 850mm (33.5 inches).

FK2:	Laminar Sealing Rings for pistons of internal combustion engines, compressors, pneumatics and hydraulics, shock absorbers etc.
FK3:	Single wound Laminar Rings as grease seals for plain and roller bearings.
FK4:	Laminar Sealing Rings for pistons in freeform and drop forging machines, presses, hydraulic controls and distributors.
FK5 / FK5-HFL:	"FK5-HFL": Double wound Laminar Sealing Rings for compensators in exhaust-pipe systems of combustion engines, turbines, continuous casting equipment etc.
FK6:	Double wound Laminar Sealing Rings as seals for grease lubricated ball and roller bearings in especially demanding applications; also for very high speeds.
FK8:	Complete seal unit with plastic ring carrier for grease lubricated axle bearing.
