  • Low-Maintenance COMBI Seals | Reduce Seal Failures and Service Costs in Harsh Conditions

    Repeated seal changes, emergency bearing work and frequent relubrication can turn a small sealing problem into a major maintenance cost. These low-maintenance COMBI seals are designed for equipment exposed to dust, mud, grit and splash, where contamination is a common cause of premature wear. The integrated sealing concept helps reduce external contaminant entry while supporting lubricant retention around rotating components. By matching the seal to actual shaft dimensions, housing geometry, speed, lubricant, temperature and environmental exposure, users can target longer service intervals, fewer contamination-driven failures and more predictable maintenance planning.

Description
Repeated seal changes, emergency bearing work and frequent relubrication can turn a small sealing problem into a major maintenance cost. These low-maintenance COMBI seals are designed for equipment exposed to dust, mud, grit and splash, where contamination is a common cause of premature wear. The integrated sealing concept helps reduce external contaminant entry while supporting lubricant retention around rotating components. By matching the seal to actual shaft dimensions, housing geometry, speed, lubricant, temperature and environmental exposure, users can target longer service intervals, fewer contamination-driven failures and more predictable maintenance planning.

Lower maintenance cost by addressing contamination at the sealing point

Frequent service is often a symptom of dirt reaching the bearing or lubricant escaping from the assembly. This COMBI seal focuses on both problems with an integrated barrier concept, helping maintenance teams reduce repeat interventions in harsh operating conditions.

Problems This Product Helps Solve

  • Frequent seal replacement caused by dirt exposure.

  • High labor cost from repeated maintenance access.

  • Lubricant contamination leading to bearing damage.

  • Emergency repairs that interrupt production schedules.

  • Short and unpredictable maintenance intervals.
