  • Integrated COMBI Seal Reliability Comparison | Mud-Site Failure Metrics vs Standard Oil Seals

    Seal reliability on muddy job sites should be measured with real maintenance data, not a universal percentage. Compare operating hours to first leak, contamination found behind the dirt lip, shaft scoring, replacement frequency and downtime per service event. The integrated COMBI seal is designed to improve the contamination side of that equation by adding dedicated exclusion barriers ahead of the lubricant-retention lip. For machines where standard oil seals fail after mud exposure, a controlled before-and-after comparison can show whether the upgraded barrier reduces repeat failures. Record the same shaft condition, lubricant, pressure, speed and installation method for a meaningful result.

Description
Seal reliability on muddy job sites should be measured with real maintenance data, not a universal percentage.

Use Real Failure Metrics Instead of Invented Reliability Percentages

No single service-life statistic applies to every muddy site. The useful comparison is your own equipment data: hours to leakage, dirt ingress evidence, shaft damage, service frequency and downtime. A COMBI seal provides a stronger contamination-control architecture to test against a standard oil seal under the same duty.
