  • Double Dust Lip Cassette Seal – Superior Anti-Dust Performance vs Single Lip

    A single dust lip may work in light contamination, but it can become overloaded when particle volume, vibration, or exposure time increases. This double dust lip cassette seal adds a second exclusion stage and a protected buffer zone, reducing the chance that dust reaches the primary oil lip. It is designed for operators experiencing short seal life, dirty grease, or shaft wear with basic single-lip designs. The upgraded barrier delivers stronger protection without requiring a complex external sealing system.

Description
A single dust lip may work in light contamination, but it can become overloaded when particle volume, vibration, or exposure time increases. This double dust lip cassette seal adds a second exclusion stage and a protected buffer zone, reducing the chance that dust reaches the primary oil lip. It is designed for operators experiencing short seal life, dirty grease, or shaft wear with basic single-lip designs. The upgraded barrier delivers stronger protection without requiring a complex external sealing system.

Upgrade from Single-Lip Protection to a Double Dust Barrier

Two exclusion lips share the contamination load, while the intermediate grease zone traps particles before they reach the oil-retaining lip.
