Contamination-Resistant Premium Reinforced COMBI Seal for Construction Machinery

Problem: Concrete dust, clay, rubble and washdown splash contaminate construction-machine lubricant and damage bearings.

Solution: Multiple exclusion stages and a rigid reinforced case protect axles, hubs and final drives in severe worksite conditions.

Key Benefits

• Blocks construction dust and clay

• Retains oil or grease

• Protects bearings in severe worksites
