Product description
- Design: special types, on enquiry
- Static seal on the outer diameter (in comparison to the Combi SF6)
- Combination of an additional seal against dirt from the outside in one housing
- Spring-loaded sealing lip
- Additional dust lip
- Primarily for usage in all applications with high level of soiling, e.g., in axles for off-road vehicles
- Use perferably instead of the Cassette Seal in case of superimposed rotational and translation movements.
Product advantages
- Long service life
- High resistance to dirt ingress due to the optimal positioning of sealing lip and dust lip.
Performance in relation to dirt from the outside
- High resistance to dirt from the outside. Suitable for protection against sludge.
