Keep muddy contamination away from bearings

Wet soil and abrasive grit can bypass basic seals, dilute lubricant and shorten bearing life. This COMBI seal focuses on the real failure point: stopping external contamination before it reaches the rotating interface while helping retain the lubricant the bearing needs.

Problems This Seal Helps Solve

• Repeated bearing replacement caused by mud ingress.

• Grease contamination after field operation or splash exposure.

• Premature shaft and seal wear from abrasive particles.

• Frequent maintenance caused by dirty working environments.

• Unexpected downtime on construction and mobile equipment.
