GUOMAT rubber air spring is a curved capsule made of rubber and mesh wire. The two ends of the capsule need to be connected with two steel plates and have a compressed air chamber. The rubber and network cables themselves do not provide load-carrying capacity, but are provided by the compressed air filled into the capsule. Rubber air springs are also called rubber air stroke regulators and rubber air vibration isolators according to their performance and characteristics.

• Internal filling medium

Air spring designs can use compressed air or ammonia gas. Air springs can also be filled with water or water-glycol solution. If filled with water, rust inhibitor must be added to protect the end cover. The air spring will be filled with liquid in two cases:
1. Reduce the internal air volume (thereby increasing the natural frequency of the air spring)
2. Use incompressible media. One of the reasons for this is precise positioning.
Petroleum-based fluids (which most hydraulic oils fall into) are not recommended. Lightly lubricated air is not harmful to air bags

• Internal charging pressure

Our rule of thumb is:
1. The maximum pressure of the two-line mesh airbag is 0.7MP.
We recommend a minimum safety factor of three times between maximum internal pressure and burst pressure. For example, if the required pressure is 0.7MP, the burst pressure should be greater than or equal to 2.1MP. For curved bladder air springs, our burst air pressure requirement reaches 3MP. For the application of GUOMAT air spring shock absorbers, the maximum pressure of the two-wire mesh air spring is best limited to within 0.7MP, and the maximum pressure of the high-strength air spring (special requirements for thickened four-layer cords is best limited to 1.2MP)

• Temperature

Standard air bags. Our company's standard industrial air spring is a rubber product made of natural rubber as the main body and vulcanized with various rubber compound formulas. The working temperature should be limited to the range of -40℃-70℃.

• Fatigue life

According to the experimental test fatigue life standard, the GUOMAT bladder rubber air spring has not been damaged after vibrating 3 million times under the conditions of 0.5MP gas, amplitude 40mm, and frequency 2.7Hz (160 times/min).

• Pollution

A protective cover should be used to protect the bladder from exposure to hot metal, sand, petroleum-based liquids, acids, etc. The airbag can withstand a certain amount of pollution in most cases (liquid pollution such as acid, weak acid and alkali environments are allowed to be used, but it will affect the service life of the airbag to a certain extent)

• Storage

Best stored in a dark, dry room temperature environment

Guangzhou Guomat Air Spring Co., Ltd. is located in Guangzhou, about 15min’s drive from Baiyun Airport. Our mainly products are air spring, rubber bellows, air suspension spring, air suspension compressor and refitted suspension system. They are widely used in bus, truck, cabin, vehicles’ seat, luxurious car and industrial machine field.

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.
