Comparison of Characteristics of Air Springs, Traditional Springs and Hydraulic Systems
| Characteristic |
Air Spring |
Traditional Metal Spring (Coil/Leaf) |
Hydraulic System |
| Stiffness Adjustability |
Excellent. Stiffness and load capacity can be easily and quickly altered by adjusting air pressure. |
Fixed. Stiffness is unchangeable once manufactured. |
Good. Adjustable via valves and pumps, but response speed and precision may be inferior to pneumatic systems. |
| Height Adjustability |
Excellent. Can maintain a consistent height under varying loads or change height as needed. |
Fixed. Height varies with the load. |
Good. Position control is achievable, but the system is more complex. |
| Vibration & Noise |
Excellent. Air provides outstanding vibration isolation and sound damping, resulting in very quiet operation. |
Poor. Prone to transmitting high-frequency vibrations and potential noise from metal contact. |
Average. Hydraulic pumps generate noise, and fluid flow can cause vibrations. |
| Ride Comfort |
Excellent. Its elastic properties are closer to the ideal linear characteristic, providing a very smooth and soft motion experience. |
Average. Can produce a harsh, jolting sensation. |
Good. But may exhibit slight shuddering and hysteresis. |
| Maintenance & Reliability |
Good. Relatively simple system. Main maintenance points are air tightness and filters. |
Simple & Reliable. Requires almost no maintenance, but fatigue failure must be considered. |
Complex. Requires maintenance of hydraulic fluid, seals, pumps, and valves. High risk of leaks. |
| Cost |
Medium to High |

About Air Spring
According to the structure of the air bag, the air spring can be divided into three types: bag type, membrane type and composite type.
The bladder-type air spring consists of a rubber bladder with cords and compressed air enclosed in it. The inner layer of the airbag is made of air-tight rubber, while the outer layer is made of oil-resistant rubber. Airbags are generally made of two sections, but there are also single sections or three or four sections. The more the number of sections, the better the elasticity. There is a steel waist ring between the sections, so that the middle part will not expand radially and prevent the two sections from rubbing against each other. The upper and lower covers of the airbag seal the airbag.
This one is triple convolutions bladder air spring that can replace Fire-stone W01-358-8030/38. This one is also an industrial air spring, which can be widely used in some industrial equipment, such as paper machinery, straightening machines, precision instruments, etc. The industrial application design diagram is as follows.
