Freudenberg designs new seal to cut contamination, improve top-speed performance

Maximum efficiency under extreme operating conditions is critical for off-highway machinery. Downtime and malfunctions lead to reductions in profitability. Freudenberg-NOK Sealing Technologies developed the Cassette-S4 off-highway industrial seal to meet the demands of mobile machinery markets by enabling long-term reliability and power in harsh conditions with no speed, temperature, or pressure limitations.

The Cassette-S4 features a three-component sealing configuration that protects all functional parts in a single component, reducing part complexity and accidental damage during installation. Robust to contamination and damage due to handling, the Cassette-S4 radial shaft seal is made up of multiple components.
