The Freudenberg CASSETTE-S4 seal solution for construction and agriculture mobile machinery wheel hubs and undercarriage applications was developed to exceed performance in harsh operating conditions.

Sealing function and tailored contamination protection, combined in one single part
All functional parts of the seal (sealing lip, optimized lip working surface, dirt exclusion lips, dedicated counter-surfaces and internal lubrication) are protected inside the closed design—reduces number of components to be managed and reduces risk of accidental damage during handling and assembly
Shaft machining and surface finishing requirements are much lower than standard sealing solutions: cassette-to-shaft contact is limited to static sealing function
No wear traces on the shaft during operation, no rework nor repositioning needed during service
Plug and play; easy to install and replace

Static sealing function:

OD: rubber + metal (typically)
ID: full rubber

Dynamic sealing function:

Freudenberg lip design with proprietary material according to given application conditions
Optimized seal working surface

Dirt exclusion function:

Standard steel and stainless steel external cover
Five internal dust lips
Lifetime internal lubrication
