Air suspension piston

The air suspension piston is a critical component that must be strong and stiff enough to support the weight of the heavy-duty truck. Since the rubber air spring is moving across the piston, the material must have good lubricity and wear resistance. The ease of molding is critical in achieving a good surface in a heavy part like this piston, as it contributes to the wear resistance.

Ascend's Vydyne R533H is ideal for this application due to its balance of strength and stiffness. It needs additional wear properties to work with the moving air spring. The ease of molding is also critical in a large part such as this. This solution has been approved and proved in production at multiple global OEMs.
