Explanation of common terms in air spring
1. Effective bearing area and effective diameter
When the air spring is filled with compressed air to support the load, the effective area of the pressure is called the effective area. For axisymmetric air springs, the effective diameter can be calculated. For example, F-400-5, where 400mm is the effective diameter of the air spring.
2. Design height (H)
The so-called design height refers to the natural height of the rubber air spring. Usually the air spring expands and contracts around this height. When the air spring is used as a stroke adjuster, the design height has no specific meaning.
3. Commonly used maximum stroke
The allowable maximum stretch and minimum compression heights are specified according to the fatigue and damage of the curvature.
4. Use the highest internal pressure
The maximum inflation pressure allowed by the air spring

Feature

Long service life, self-sealing type Excellent durability due to less rubber deformation during expansion and contraction Maintenance is very simple, there is no friction sliding part, so there is no need for lubrication; installation height can be reduced, compared with other springs, can The installation height is reduced, and the stroke can be effectively increased to obtain elastic and soft spring parameters. The load is large and the elasticity is soft, and the anti-vibration performance is superior; the output of the bearing capacity is variable, and the bearing capacity can be changed in a wide range by changing the internal pressure; the height Controllable, if it is used together with height adjustment valve, it can maintain a constant height for different loads; it has damping effect, if it is used together with auxiliary air chamber and throttle valve, it can obtain excellent damping effect, so that the resonance amplitude can be reduced; easy to install, The structure is simple, and the installation and disassembly are simple and easy.

GUOMAT Factory gate：

Established in 2008, Our company covers 20,000㎡ and is located in Taihe Town Baiyun District. With the rapid development of our company, we are equipped with modernized workshop and advanced rubber air springs equipments now. We are the first company who started air spring business and has become one of the largest air spring manufacturing bases in China.

In 2017, we launched a collaboration with High Tech of US customers to customize the products of our customers and the logo of our customers. Every year, there are about 10,000 orders. In continuous cooperation, the products meet the international inspection standard ISO/TS16949:2009, and the customers are very satisfied with the products produced. This is our high recognition from American customers and also gives us Great motivation.

In 2018, we started cooperation with German GmbH, mainly industrial air springs, which are suitable for industrial equipment. We have successfully developed and produced the natural air-seal of the skin to reach the 700mm flanged air spring, the customer's annual demand is a few hundred.

With the development of business and demand for customers, our company introduced business with TomLog Corporation in 2010, our strategic cooperative partner in Taiwan. Then we developed air compressor program and air spring related business, in 2015, America Goodyear Corporation met with the transfer of shares in the North American plant, our company was granted with sale agent for air springs in China, providing more choice for our customers. Our company adopts the most advanced domestic air spring processing equipment and international production technology. Combined with unique production process, our company strictly execute international standards for production and spare no efforts to create the world-class products. We will endeavor to make air spring widely used at home and abroad, and let more and more customers to enjoy the best damping effect.
