  • Closed Assembly Cassette Seal – Stop Progressive Dust Accumulation

    Inside a closed cassette assembly, dust can advance in stages: outer-lip loading, grease contamination, inner-lip abrasion, shaft polishing, and final leakage. Because the damage is hidden, operators may not act until failure is complete. This closed assembly cassette seal interrupts that progression with staged exclusion lips, a long labyrinth path, and separated grease zones. It is designed for rotary systems that need reliable contamination control without frequent access or disassembly.

Break the Dust Accumulation Process Inside Closed Seal Assemblies

Staged barriers slow, trap, and isolate particles before they reach the primary sealing interface, protecting grease, lips, shafts, and bearings.
