  • COMBI Seal for Pile Drivers – Reinforced Dust Shield Stops Concrete Dust & Debris Penetration

    This reinforced COMBI seal is designed for pile drivers and foundation machinery exposed to concrete dust, soil, mud, moisture and impact-generated debris. Its metal-cased construction provides secure installation, while the multi-lip sealing system retains lubricant and forms a strong external dust shield around rotating shafts, gearboxes, rollers and bearing housings. The seal helps reduce contamination, abrasive wear and lubricant loss during repetitive hammering, vibration and heavy-duty foundation work. It is suitable for hydraulic pile drivers, vibratory hammers, drilling attachments and related construction equipment. NBR, FKM and application-specific compounds can be selected according to temperature, lubricant and environmental exposure, with carbon steel or stainless steel case options and optional corrosion-resistant treatments. Shaft diameter, housing bore, width, hardness, spring load and lip geometry can be customized from drawings or physical samples. Compared with standard single-lip seals, the COMBI design offers stronger contamination exclusion and supports longer service intervals, fewer unexpected repairs and improved equipment reliability on demanding construction sites.
