Areas of application
Sealing of rotating machine elements such as shafts, hubs and axles.

Function
The WAK FKM is a rotary shaft seal for rotating or pivoting shafts with optional protective lip sealing action (WAG FKM) on the side facing away from the medium, against dirt accumulation from the outside. The grooved outer sheath provides improved static sealing for housings with greater thermal expansion because it has a higher press fit allowance. It also prevents permanent skew of the rotary shaft seal. In addition, installation is facilitated because less press-fit force is required.
