Description
Overview:
This driveshaft seal is a high-performance rotary oil seal for JCB driveline components, manufactured by Corteco. Made from durable NBR (Nitrile Butadiene Rubber), it is built to retain lubrication and block dirt, grit, and water at the driveshaft or axle interface. It is suitable for heavy-duty construction and agricultural machines, including JCB backhoe loaders such as the 2CX and 3CX. The seal features a spring-loaded primary lip for consistent contact pressure and an additional dust lip for extra protection. Its COMBI SF6 Simmerring design, with an integrated PU element, supports reliable sealing even with small axial movements. Supplied as a direct replacement for JCB part 904/50040, it helps maintain efficiency, reduce oil loss, and protect bearings and gears in harsh environments.
Key Features:
- NBR construction for strong resistance to mineral oils, wear, and ageing
- Spring-loaded sealing lip maintains contact under vibration and shaft runout
- Secondary dust lip shields against mud, sand, and slurry ingress
- COMBI SF6 Simmerring structure combines elements for robust radial and axial sealing
- Integrated PU element accommodates small axial motions without losing sealing performance
- Designed for high-soiling applications such as off-road axles and industrial drives
- Helps prevent oil leaks and contamination, supporting longer service intervals
- Direct replacement for JCB 904/50040 with multiple cross-references for easy identification
- Suitable for selected JCB Backhoe Loaders, Fastrac, Telescopic Handlers, and Rough Terrain Fork Lifts
- Straightforward fit using standard workshop tools; no special modifications typically required
Typical Applications:
Used on axle input shafts, differential pinions, transmission outputs, and drive hubs where oil retention and dirt exclusion are critical. Ideal for JCB backhoe loaders, telehandlers, and rough terrain forklifts operating in mud, dust, and abrasive environments. Also well-suited to other off-road machinery and industrial drives requiring dependable shaft sealing under shock loads and frequent articulation.
Also known as:
Rotary shaft seal, radial oil seal, lip seal, garter spring seal, axle input seal, hub seal, rotary simring, dual-lip seal, combi oil seal.
