Feature

●Long service life
●Additional dust lip
●Spring-loaded sealing lip
●Use preferably instead of the DMHUI Cassette Seal in case of superimposed rotational and translation movements
●Combination of a oil seal and an additional seal against dirt from the outside in one housing. High resistance to dirt from the outside. Suitable for protection against sludge. Primarily for usage in all applications with high level of soiling, e.g., in axles for off-road vehicles
