  • Mud-Proof COMBI Seal | Off-Road Shaft & Hub Protection for Wet Dirt and Slurry Exposure

    Off-road machinery often works through wet soil, slurry and abrasive mud that packs around shafts and wheel ends. When this contamination reaches the sealing interface, lubricant can become diluted or polluted, bearings wear faster and maintenance crews face repeated hub or shaft service. This mud-proof COMBI seal is designed for vehicles and machinery exposed to persistent wet dirt, combining an external contamination barrier with lubricant-retention support. It can be matched to shaft diameter, hub geometry, lubricant, temperature, speed and installation space for off-road equipment, construction machines and other mobile applications where reliable sealing is needed to reduce mud-driven failures and costly downtime.

Description
Off-road machinery often works through wet soil, slurry and abrasive mud that packs around shafts and wheel ends. When this contamination reaches the sealing interface, lubricant can become diluted or polluted, bearings wear faster and maintenance crews face repeated hub or shaft service. This mud-proof COMBI seal is designed for vehicles and machinery exposed to persistent wet dirt, combining an external contamination barrier with lubricant-retention support. It can be matched to shaft diameter, hub geometry, lubricant, temperature, speed and installation space for off-road equipment, construction machines and other mobile applications where reliable sealing is needed to reduce mud-driven failures and costly downtime.

Stop wet mud from turning wheel-end service into a recurring problem

Sticky mud and slurry can remain packed around the seal for hours, forcing contaminants toward the bearing cavity. This COMBI seal helps create a stronger barrier against wet dirt while supporting lubricant retention inside the rotating assembly.

Problems Solved

  • Wet mud entering hub and shaft sealing points.

  • Slurry contaminating grease or oil.

  • Repeated wheel-end and bearing maintenance.

  • Abrasive wet dirt damaging sealing surfaces.

  • Off-road downtime caused by contamination.
