Why choose Guomat air spring shock absorber rather than spiral spring or other type of shock absorber?

Advantage 1: excellent damping capacity

Guomat air spring shock absorbers have high vibration isolation capability among all types of vibration shock absorbers. The natural frequency of the system can be as low as 1 hz. The system's natural frequency can be even lower if an additional air storage chamber is added. In order to achieve the same effect, the static deformation of traditional spiral spring shock absorbers is required to reach 220 mm.

Advantage 2: stable damping effect

The unique feature of Guomat air spring shock absorbers is that the natural frequency of the system does not change significantly when the load changes. This characteristic, combined with precise height control, makes it particularly suitable for mounting Guomat air spring shock absorbers at various mounting points on equipment with uneven loads.

Advantage 3: precise height control

Guomat air spring shock absorbers provide precise height control by adjusting the internal air pressure. This feature eliminates fatigue and one-time setup problems common in other types of isolators.

Advantage 4: wide size range
Guomat air spring shock absorbers have vibration isolation loads from 10KG to more than 10 tons per installation point.

Advantage 5: compact installation height
Guomat air spring shock absorbers can withstand these loads at mounting heights as low as 50 mm for vibration reduction. To achieve the same vibration isolation effect, the helical spring requires a free height of 135 mm to 645 mm.

Advantage 6: prolong the service life of the equipment
Guomat air spring shock absorbers significantly extend the service life of equipment through their excellent damping capacity.

Advantage 7: effectively reduce noise

Guomat air spring shock absorbers reduce noise transmitted through the structure. Air spring shock absorbers themselves also do not produce noise because they do not have the flutter problems of traditional helical springs.

Advantage 8: wide use
Guomat air spring shock absorbers can not only be used to protect the mechanical structure parts which produce vibration, but also widely used to isolate the vibration transmitted to precision machinery through the structure.
