Break the cycle of dirt ingress, dirty lubricant and repeat failures

In highly contaminated environments, a basic seal may not provide enough protection. Dirt that reaches the bearing cavity can turn lubricant into an abrasive mixture and create recurring maintenance problems. This integrated COMBI seal adds a stronger contamination-control concept around the rotating interface.

Customer Problems Addressed

• Continuous dirt ingress around rotating shafts.

• Lubricant contaminated by soil, dust and process debris.

• Accelerated bearing and sealing-surface wear.

• Frequent maintenance in high-contamination locations.

• Unexpected failures after ordinary seals lose effectiveness.
