A reinforced dustproof COMBI seal designed for continuous-duty machinery in dusty open mines and similarly harsh field environments. The rigid metal case and multiple protective lips help retain oil or grease, block mineral dust and grit, reduce abrasive wear, and support reliable long-term shaft operation.
This heavy-duty COMBI seal is engineered for rotating assemblies exposed to continuous dust, sand, stone powder, and debris. Its reinforced case provides stable housing retention, while the oil lip and external dust lips protect lubricant and internal components. It is suitable for agricultural and off-highway axles, hubs, gear units, and final drives. Custom configurations are available.
