Industrial Bellows Actuator WBZ 320-E Weforma Double Convoluted Air Spring G3/4 Air Hole

Industrial Bellows Actuator WBZ 320-E Weforma Double Convoluted Air Spring G3/4 Air Hole

Product Description

A Double Convoluted Air Spring is a type of pneumatic suspension component featuring two bellows (convolutions) for enhanced load-bearing capacity and flexibility. Commonly used in heavy-duty vehicles, industrial machinery, and railway systems, it adjusts air pressure to accommodate varying loads while maintaining optimal height. Its dual-convolution structure allows greater travel and damping efficiency, reducing wear and fatigue. This design ensures durability, adaptability, and consistent performance under dynamic conditions, making it ideal for applications requiring robust suspension solutions.

Maintaining Industrial Air Springs

1. Regular Inspection
Appearance Inspection:

• Inspect the air spring surface for cracks, wear, bulges, or scratches, especially at wrinkles and seams.
• Inspect metal parts (such as end caps and pistons) for rust or deformation.

Connections:

• Ensure that there are no leaks in the air pipes and joints (use soapy water to check for bubbles).
• Tighten bolts, flanges, and other fasteners to prevent loosening.

2. Cleaning and Maintenance
Removing Dirt:

• Regularly clean dust, oil, or chemical residue from the air spring surface with a soft cloth or brush (avoid using corrosive cleaners).

Corrosion Prevention:

• Metal parts can be coated with rust-inhibiting oil, especially in humid or corrosive environments.

3. Air Pressure Management
Pressure Monitoring:

• Use a pressure gauge to check that the operating air pressure is within the rated range (refer to the product manual).
• Avoid operating at over- or under-pressure, as this will accelerate aging and affect performance.

Leak Test:

• After inflation, allow the spring to rest for a period of time to observe whether the pressure drops too quickly.

4. Lubrication and Maintenance
Moving Parts:

• Apply silicone-based lubricant to pistons and sliding parts (to prevent petroleum-based grease from corroding rubber).

Seals:

• Inspect seals for deterioration and replace if necessary.

5. Load and Operating Environment
Avoid Overloading:

• Ensure that the load does not exceed the design limit, as this may cause the airbag to deform or rupture.

Environmental Control:

• Keep away from high-temperature sources, ozone (such as near motors), and sharp objects.
• If used in extreme temperature or chemical environments, select a more weather-resistant material (such as a fluoroelastomer airbag).

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.
