Maximum efficiency under extreme operating conditions is crucial for agricultural machinery. The equipment has to function as long and reliably as possible, whether it is used in demanding temperatures, in water and mud, or in dust-filled fields. That’s because downtime and malfunctions, especially during sowing and harvesting, lead to major reductions in profitability.
Freudenberg Sealing Technologies has long stood for reliability and longevity in its products for the agricultural sector, as is the case with its cassette seals, which have proven themselves fully for decades in the most adverse work environments.
Freudenberg cassette seals are robust pinion and wheel hub seals with a dirt-repelling multi-labyrinth in a single housing. This provides the maximum sealing effect with minimal friction. In addition, a finished seal running surface is integrated into the cassette seal. In this way, the shaft does not need to be hardened and ground separately. Additional dirt seals are not required either. With the new S4 cassette seal, Freudenberg has further improved an already successful product.
The new cassette seal has another advantage: Large tractors and harvesters are often equipped with crawler drives.
Due to their greater contact area, they compress the soil less. Until now they had to be fitted with complicated mechanical slide ring seals.
New designs of cassette seals can also improve the sealing of axles without reducing driving speeds on roads. The cassette seal HS-EVO is one example. In this case, the overheating of the seal’s elastomer is prevented, enabling it to offer a high degree of protection even at high rotational speeds and naturally with outstanding resistance to contamination.
