How to Buy the Right Size Air Spring
1. Determine the type of air spring
Air springs are mainly divided into the following types. Different uses require different size selection methods:
Bag air spring (such as air bags used alone, suitable for suspension systems)
Sleeve air spring (with metal shell, commonly used in automobiles or industrial shock absorption)
Membrane air spring (flat design, used in space-constrained scenarios)
Selection suggestion: Choose the appropriate type according to the installation location and purpose.

2. Key size parameters
Before purchasing, the following dimensions must be measured or confirmed (units are usually millimeters or inches):

(1) Installation size
Inner diameter (ID): The hole diameter of the air bag mounting bolt or bracket.

Outer diameter (OD): The maximum diameter of the air bag after inflation, ensuring that it does not interfere with surrounding components.

Height (free height & working height):

Free height: The natural height when not inflated.

Working height: The height of normal use after inflation (affects the stroke and load capacity).

(2) Stroke
The limit range of air bag compression/extension must meet the movement requirements in actual applications.

(3) Load Capacity
Select the appropriate load range according to the weight of the equipment (e.g. if a single airbag needs to support 200kg, select a model with a rated load ≥ 200kg).
