What is the structure of this air spring?

It features a Double Cylinder structure and is Gas-Filled, suitable for Rear position.

How does the air spring provide damping?

An orifice between the main and auxiliary air chambers creates a pressure difference during vibration, where air flow resistance absorbs energy to provide damping.

Is this product suitable for OEM applications?

Yes, the product is listed as OEM suitable and the brand is OEM, indicating it is designed for original equipment manufacturing.

Key features

Non-linear Elastic Control: Ideal non-linear characteristics effectively limit amplitude, avoid resonance, and prevent shock.

Adjustable Stiffness: Stiffness is adjustable via air chamber volume or pressure to suit different load requirements.

Load-Independent Frequency: Natural frequency remains almost unchanged under different loads for consistent vibration isolation.

Height Stability: Vehicle body height remains constant despite load changes when using a height adjustment device.

Superior Sound Insulation: Rubber and air materials absorb high-frequency vibration and provide excellent sound insulation.

Lightweight Design: Significantly lighter than steel springs, composed mainly of rubber bladder and weightless air.

Multi-Load Compatibility: Same air spring can meet multiple load requirements by changing internal pressure for different capacities.

Integrated Damping Effect: Orifice between chambers creates pressure difference and resistance, providing effective damping.

AI-Powered supplier vetting

SummaryThe supplier is a limited company with three employees, no stated parent-group affiliation, and a valid import/export license. It is identified as a professional technical supplier offering 3D software design, ODM, OEM for popular brands, and multiple forms of customization. However, it launched no new products in the past year and has no available SDK. Service-management controls are weak: no written procedures or records were provided for supplier assessment, corrective and preventive actions, or complaint handling. The supplier has no inventory, overseas warehouse, showroom, agent, or branch service capability. Its business scope covers metal products, building materials, construction-related products, electronic special equipment, and installation or maintenance services. Financial records are referenced for 2021–2023, but the provided information does not establish financial strength. No certifications, customer cases, or production assets/capacity are explicitly documented.

Supplier typeThe supplier is explicitly identified as a professional technical supplier and a limited company. Its stated business scope covers metal products, building materials, electronic special equipment, and installation or maintenance services; it has three employees, no stated group affiliation, and a valid import/export license.

CertificationsThe supplier is reported to hold a valid import/export license. No other certification information is provided, so certification coverage beyond trade licensing cannot be assessed.

After-Sales capabilityThe supplier has no overseas warehouse, showroom, agent, or branch service capability. It also has no written procedures or records for effective complaint handling or corrective and preventive actions, indicating explicitly limited documented after-sales support controls.

R&D capabilityThe supplier reports professional R&D capability, 3D software design services, ODM services, and OEM services for popular brands. Conversely, it launched no new products in the past year and has no available SDK, so its broader innovation strength is mixed.

Customization capabilityThe supplier explicitly offers customization from samples, designs, full customization, minor customization, and flexible customization, as well as 3D software design and ODM services. These statements provide direct evidence of broad customization capability.

Client casesThe supplier states that it provides OEM services for popular brands, which is evidence of serving at least that type of customer. However, no customer names, project details, or verifiable case records are supplied.

Product Q&A

Q:What is the main material of the air spring?

The air spring is made of Rubber+Steel, specifically consisting of a rubber bag and steel covers.

Q:How does the air spring handle different loads?

The stiffness changes with the load, keeping the natural frequency almost unchanged. It can also bear multiple loads by adjusting internal pressure.

Q:Does the air spring affect vehicle height under load?

No, after installing the height adjustment device, the vehicle body height does not change with the increase or decrease of the load.

Q:What are the advantages over steel springs?

Air springs are lighter, provide better sound insulation, absorb high-frequency vibrations, and offer adjustable stiffness and non-linear elastic characteristics.

Q:Can the stiffness of the air spring be adjusted?

Yes, the stiffness can be adjusted by changing the volume of the air chamber or the pressure of the inner cavity.
