  • Dust-Resistant COMBI Seal | Fine-Particle Protection for Industrial Rotating Equipment

    Fine industrial dust can penetrate small sealing gaps, mix with grease and create abrasive wear that is difficult to detect until bearings become noisy, hot or unreliable. This dust-resistant COMBI seal is designed for rotating equipment operating around powder, dry soil, mineral dust and process particles. Its integrated barrier helps reduce particle ingress while supporting lubricant retention at the shaft or bearing interface. For plants dealing with frequent relubrication, dirty bearings or short seal life, the seal can be matched to shaft diameter, housing size, speed, temperature, lubricant and contamination severity. The result is a more application-focused solution for improving reliability and reducing dust-driven maintenance.

Description
Fine industrial dust can penetrate small sealing gaps, mix with grease and create abrasive wear that is difficult to detect until bearings become noisy, hot or unreliable.

Keep fine dust from turning lubricant into abrasive paste

Fine particles can enter unnoticed, contaminate grease and gradually damage bearings and shafts. This dust-resistant COMBI seal helps limit that ingress while supporting lubricant retention at critical rotating interfaces.

Problems Solved

  • Fine dust entering bearing housings.

  • Powder contaminating grease.

  • Short seal life in dry dusty plants.

  • Frequent relubrication and inspection.

  • Dust-driven bearing wear and downtime.
