A heavy-duty COMBI seal for mining vehicles and related mobile equipment operating under continuous dust exposure. The reinforced case and advanced multi-lip design help retain hydraulic or gear lubricant, prevent abrasive particle ingress, and support stable shaft, bearing, and drive-system performance in harsh working environments.
This mining vehicle COMBI seal provides a combined oil-retaining and contamination-excluding solution for shafts exposed to coal dust, stone powder, sand, mud, and debris. Its reinforced structure supports secure housing retention, while the external dust lips protect internal lubricant and rotating components. Custom sizes, materials, and hardness levels are available for demanding equipment.
