FUNCTION

Dynamic sealing of rotating shafts, independent of direction of rotation
Good static seal between sealing lip and shaft at standstill
Protective lip against dirt accumulation from outside
Rubberized outer jacket ensures tight fit and seal to housing borePRODUCT ADVANTAGES
- Good static sealing effect with low-viscosity or gaseous media
- Low friction
- Compensates for thermal expansion, e.g. in light metal housings, good sealing effect with greater roughness and with split housings
- Long service life
- Reliable design with broad application spectrum for moderately demanding applications in general industry
COMMON APPLICATIONS
- Sealing of rotating machine elements (shafts, hubs, axles)
