A reinforced anti-contamination COMBI seal designed to protect bearing assemblies from dust intrusion, sand, soil, and abrasive debris. The metal-supported case and multi-lip arrangement help retain lubricant, isolate the bearing cavity from external particles, reduce surface wear, and extend service life in agricultural and heavy machinery.
This reinforced COMBI radial shaft seal provides dual protection for rotating bearing systems by retaining oil or grease and blocking external contamination. It is suitable for hubs, axles, gearboxes, and final drives exposed to dusty or muddy conditions. The rigid case improves housing stability, while customizable sizes, elastomers, and hardness levels support different equipment applications.
