Agricultural environments expose equipment to mud, dust, moisture, and temperature swings. A major farm machinery manufacturer struggled with axle seal failures in tractors working year-round in open fields. These failures led to frequent oil leaks and reduced axle life.

Application Background

The affected tractors were deployed across mixed terrain, with daily exposure to water and abrasive soil. The previous sealing setup allowed contaminant ingress, forcing monthly servicing and premature bearing replacements.

COMBI Seal Implementation

After a review of operational cycles, COMBI proposed a multi-lip sealing profile featuring a central mud expulsion groove and hydrodynamic lip geometry. Seals were made with flexible, wear-resistant compounds suited for agricultural debris environments.

Measured Impact

The farm reported over 14 months of uninterrupted axle performance with no leakage or contamination. Maintenance frequency dropped from once a month to once per quarter, and axle component lifespan increased by over 35%.

Testimonial

The engineering lead commented: “We’ve never seen seals last this long in field conditions. COMBI’s design clearly understands the realities of agricultural wear and tear.”
