Single Turn Laminar Sealing Rings Combined for Bores Series FK3 AS
Single wound laminar sealing rings "FK3 ASK" are used as a grease seal for roller and plain bearings and they protect,
if greased, against dust entry and ambient moisture. Due to the increased labyrinth effect, the sealing effect is optimized
by the additional sealing of the groove base diameter.
The "FK3 AS" or "FK3 ASK" assemblies are normally preferred over the "FK3 IS" or "FK3 ISK" assemblies due to their
easier installation into the grooves. Depending on the applications or the technical requirements, the ring carriers can
be manufactured from steel, cast iron, light alloy or plastics.
