Cassette Seals

Cassette seals are specifically developed to provide excellent sealing efficiency for lubrication media while offering maximum protection against external contamination.

Commonly used in wheel-end applications for off-highway and military vehicles, these seals are ideal for retaining dense lubricants such as oil or grease. They are also suitable for other driveline areas that require a simple, high-performance sealing solution.

Temperature Range

Performs reliably across a wide temperature spectrum, ensuring consistent sealing in extreme conditions

High-Speed Capability

Designed to operate at high rotational speeds for demanding applications without compromising seal integrity

Contaminant Protection

Multi-lip design with dirt-exclusion features provide defence against solid and liquid contaminants

Prevent Leakage

Optimised sealing geometry ensures superior oil retention and minimises leakage for extended service life

Seal Designs & Features

• Integrated wear sleeve with rubber coated inner diameter for reliable sealing and easy installation
• Removes the need for shaft preparation and prevents shaft grooving, allowing quick rebuilds without costly repairs
• Multi lip design with strong dirt exclusion for high protection against contaminants
• Optimised for oil retention and reduced friction to improve efficiency and service life
• Compact design for straightforward integration into driveline systems
• Available in high performance elastomers such as Nitrile (NBR) and Fluoroelastomer (FKM), with options for demanding applications

Engineered for your application

Each cassette seal is designed around your application requirements, delivering consistent performance and trouble‑free integration within your driveline system:
