Seal ring for Demag AC-395

The seal ring 50542098 serves as a barrier on the first axle of heavy-duty mobile cranes. By creating a tight interface around the rotating axle shaft, it retains essential lubricants within the axle housing while simultaneously blocking the ingress of dirt, moisture, and debris. This containment is necessary to preserve the integrity of the internal bearings and gear sets during operation.

This component is compatible with Demag AC-395, AC-395 Serie-76011 U150, and AC615 models. It is engineered to meet the specific fitment requirements for the first axle assembly in these machines, ensuring proper seating against the shaft surface to maintain a consistent seal under varying operational speeds and environmental conditions.

Seal rings of this type function by utilizing a flexible lip that maintains contact with the rotating shaft. In axle systems, these seals are critical for preventing the loss of oil or grease, which would otherwise lead to friction, overheating, and accelerated wear of mechanical components. Regular inspection and replacement of these seals help maintain the lubrication circuit and protect the transmission and steering mechanisms from premature failure caused by fluid loss or contamination.
