Freudenberg Energy Saving Seal (ESS)

Thanks to the combination of elastomers capable of withstanding extraordinarily high thermal loads and a friction-optimized sealing lip, the energy-saving seal (ESS) enables the power loss in drive assemblies to be greatly reduced.

The radial shaft seal ESS improves sealing performance by reducing friction between the seal lip and crankshaft through a reduction in radial load of 50% when compared to sprung rubber lip seals and 75% when compared to PTFE lip seals.
