Heavy Equipment COMBI Seal – Reinforced Multi-Lip Design Provides All-Around Dust & Pollution Protection

This heavy equipment COMBI seal uses a reinforced multi-lip design to provide broad protection against dust, dirt, mud, water, metal particles and other industrial contamination. The rigid metal case supports secure installation, while the primary sealing lip retains oil or grease and the external lips create multiple barriers around rotating shafts, hubs, bearings and gearbox interfaces. It is suitable for agricultural machinery, construction equipment, mining vehicles, conveyors, material handling systems and other heavy-duty applications operating in polluted environments. By limiting contaminant ingress and lubricant loss, the seal helps reduce shaft scoring, bearing wear, overheating and premature component failure. NBR, FKM and application-specific elastomer compounds can be selected according to temperature, lubricant and chemical exposure, with carbon steel or stainless steel case options and optional corrosion-resistant treatments. Dimensions, hardness, lip profile and spring load can be customized from drawings or samples. This COMBI seal is suitable for OEM production and replacement maintenance, supporting longer service intervals, improved equipment reliability and lower total maintenance costs.
