A premium COMBI dust seal designed to safeguard final-drive shafts and gear assemblies from external dirt, sand, mud, and abrasive debris. Its reinforced case and multi-lip configuration help retain gear oil, protect bearings and shaft surfaces, reduce contamination-related wear, and support dependable agricultural and heavy-equipment operation.
This premium reinforced COMBI seal combines a primary lubricant-retaining lip with auxiliary external dust barriers. It is suitable for final drives, axle ends, hubs, and gear housings exposed to severe field contamination. The rigid metal case supports stable press-fit installation, while customizable elastomers and dimensions help match different lubricants, temperatures, speeds, and equipment requirements.
