Zhejiang Oulida Hydraulic Machinery Co., Ltd.
Zhejiang Oulida Hydraulic Machinery Co., Ltd.
Zhejiang Oulida Hydraulic Machinery Co., Ltd. is located in Fuyang District, Hangzhou City, Zhejiang Province. The company was established in 1993 and specializes in the development and production of gas springs. In 2012, we invested 72 million yuan to build a new forest chemical factory covering an area of 25,000 square meters. We have introduced advanced automated production lines, with a single-shift capacity of 20,000 units and an annual capacity of up to 6 million units, making us one of the largest factories in the industry domestically and internationally. OEM/ODM Lift Support Rod Gas Spring Manufacturers and Custom Gas Strut Lift Support Factory in China.
Currently, our gas springs are widely used in engine hoods, doors, and other support systems in various applications, including automotive, construction machinery, and textile industries, both domestically and internationally. In 2017, we established a cooperative management system called DMC (Design-Manufacture-Cooperate) in collaboration with DEFTA from France and MICHANG from South Korea. This collaboration focuses on design, development, and production, leveraging the expertise and management technology of DEFTA and MICHANG in supporting European, Japanese, and American systems, enhancing Oulida's capabilities in various aspects. Supply Wholesale Gas Spring Lift Support Rod.
In July 2021, our company drafted and officially released the industry standard QC/T 207 "General Gas Springs for Automobiles."
Industry knowledge
What components are lift support rod gas spring struts made of and what are their functions?
Gas springs typically consist of several key components, each serving a specific function in the operation and functionality of the device. Here are the main components of gas springs along with their functions:
Cylinder: The cylinder is the outer casing of the lift support rod gas spring struts and houses the internal components. It provides structural support and contains the compressed gas that generates the force required for operation.
Piston: The piston is a movable component inside the cylinder. It separates the gas chamber from the oil chamber and moves in response to changes in pressure, converting the energy stored in the compressed gas into mechanical force.
Seals: Seals are used to prevent gas leakage and maintain pressure within the gas spring. They are typically made of rubber or elastomeric materials and are located at various points along the piston and cylinder to ensure a tight seal.
End Fittings: End fittings are attached to the ends of the gas spring and are used to connect the spring to the objects or surfaces it is intended to support or control. End fittings come in various designs and configurations to accommodate different mounting requirements.
Rod: The rod is a cylindrical shaft that extends from one end of the gas spring and is attached to the piston. It transmits the force generated by the compressed gas to the external load or application.
Oil: Some gas springs contain oil within the cylinder to provide damping and control the speed of the piston during operation. The oil helps regulate the movement of the piston and prevents rapid fluctuations in pressure.
Valves: Valves control the flow of gas into and out of the gas spring, allowing for adjustments in pressure and damping characteristics. They may include features such as compression valves, extension valves, or adjustable damping valves depending on the specific requirements of the application.
Each of these components plays a critical role in the functionality and performance of gas springs, allowing them to provide controlled motion, support heavy loads, and operate reliably in a wide range of applications across various industries.

How Do I Select the Right Gas Spring for My Application?
Selecting the right gas spring for your application involves considering several factors to ensure optimal performance, safety, and compatibility. Here are the key steps to guide you through the selection process:
Determine Application Requirements:
Define the specific requirements of your application, including load capacity, desired stroke length, mounting orientation, and operating environment.
Calculate Load Requirements:
Determine the weight or force that the lift support rod gas spring struts needs to support or control. Consider factors such as the weight of the object being lifted or the force required for movement.
Consider Operating Conditions:
Evaluate the environmental conditions in which the gas spring will operate, including temperature extremes, humidity, exposure to chemicals or corrosive substances, and potential impact or vibration.
Choose the Correct Size and Stroke Length:
Select a gas spring with the appropriate size and stroke length to accommodate the required movement and provide sufficient force throughout the entire range of motion.
Select Mounting Orientation:
Determine the desired mounting orientation of the gas spring (e.g., vertical, horizontal, angled) and select a model that is designed to function effectively in that orientation.
Consider Damping Requirements:
Determine whether damping or controlled motion is required for your application. Some gas springs feature built-in damping mechanisms or adjustable damping options to regulate the speed of movement and prevent sudden jolts or impacts.
Evaluate Safety Considerations:
Assess safety requirements and consider features such as locking mechanisms or safety valves to prevent accidental release of pressure or uncontrolled movement.
Consult Manufacturer Specifications:
Refer to manufacturer specifications, catalogs, or technical data sheets to identify gas spring models that meet your application requirements. Pay attention to load ratings, stroke lengths, operating temperatures, and other relevant specifications.
Consider Customization Options:
Explore customization options if standard gas spring models do not fully meet your requirements. Some manufacturers offer customization services to tailor gas springs to specific applications.
Review Installation and Maintenance Guidelines:
Familiarize yourself with installation instructions and maintenance guidelines provided by the manufacturer to ensure proper installation, operation, and longevity of the gas spring.
By following these steps and carefully evaluating the requirements of your application, you can select the right gas spring to meet your specific needs and achieve optimal performance and reliability.
