  • COMBI Seal for Sprayer Wheel Hubs – Blocks Chemical Dust & Field Dirt to Maintain Seal Integrity

    This COMBI seal is designed for agricultural sprayer wheel hubs exposed to chemical dust, fertilizer residue, field dirt, moisture and abrasive soil particles. Its rigid metal case supports reliable installation, while the reinforced multi-lip structure retains lubricant and creates a durable contamination barrier around rotating hub components. The seal is suitable for self-propelled sprayers, trailed sprayers and related crop-care machinery operating across long field cycles. By limiting dust ingress and grease or oil loss, it helps protect wheel bearings, reduce shaft wear and maintain stable hub performance. NBR, FKM and application-specific elastomer options can be selected according to chemical exposure, temperature and lubricant requirements, with carbon steel or stainless steel case choices and optional corrosion-resistant treatments. Dimensions, lip geometry, hardness and spring load can be customized from drawings or samples. Compared with standard single-lip seals, the COMBI design provides stronger external exclusion and helps extend maintenance intervals, reduce replacement frequency and preserve seal integrity in demanding agricultural spraying conditions.
