66117-SAF
Air Spring
SAF-Holland

The 66117-SAF air spring offers reliable vertical support and ride-height maintenance within heavy-duty SAF-Holland suspensions. Its design centers on a robust bellows, durable end caps, and a sealed air chamber that resists ingress of moisture and contaminants. By adjusting to shifting loads, this component helps preserve axle alignment, reduces bottoming events, and mitigates road-induced vibrations that can lead to component fatigue. The system enables smoother transitions between loaded and unloaded states, improving operator comfort and reducing fatigue during long hauls. Mounting interfaces are engineered for straightforward replacement with minimal downtime, and the seal design promotes longer service life even in challenging climates. With proper maintenance and periodic checks for leaks, this air spring can contribute to lower maintenance costs and higher uptime for fleets that depend on consistent suspension performance.
