How to Choose the Right Suspension Air Spring for Your Truck
Choosing the right air spring for your truck requires consideration of multiple factors, including vehicle type, load requirements, driving conditions, and compatibility. Here is a detailed selection guide:
1. Determine vehicle information
Truck model (such as Mercedes-Benz Actros, Volvo FH, Scania R series, etc.).
Number of axles and suspension type (front suspension, rear suspension, trailer suspension, etc.).
Year of production (different years may have design differences).
2. Clarify technical parameters
Load capacity (single-axle/dual-axle load, unit: kg or lbs).
Installation dimensions:
Diameter and height (free height/compressed height) of the air spring.
Base fixing method (bolt hole spacing, flange type, etc.).
Operating pressure range (usually 5~10 bar, heavy trucks may be higher).
