A reinforced COMBI radial shaft seal engineered to retain lubricant and block dust, sand, mud, and fine particles in agricultural and off-highway machinery. Its heavy-duty metal-cased construction helps protect shafts and bearings, reduce premature seal damage, and support longer maintenance intervals in demanding field conditions.
This reinforced COMBI seal combines reliable oil retention with enhanced external contamination protection. It is suitable for agricultural axles, hubs, gearboxes, final drives, and other rotating assemblies exposed to dust, mud, crop residue, and abrasive particles. Custom materials and dimensions are available for different operating conditions.
