Effortless Precision: Your Complete Guide to Mounting Constant Force Springs

source:Qianye Precision time:2024-2-18

Constant force springs are invaluable components known for their ability to provide a near-constant level of force throughout their deflection. Mounting these springs with precision is essential to ensure optimal performance. In this comprehensive guide, we’ll walk you through the step-by-step process of mounting constant force springs with ease and accuracy.

Understanding Constant Force Springs:

Before diving into the mounting process, it’s crucial to have a basic understanding of constant force springs. These springs exert a consistent force over their extension or compression, making them ideal for various applications, from retractable cords to counterbalance mechanisms.

Tools and Materials:

To begin the mounting process, gather the necessary tools and materials. You’ll typically need a set of screwdrivers, pliers, a measuring tape, and safety equipment. Ensure that you have the correct constant force springs for your application, considering factors such as load capacity and desired deflection.

Safety First

Before handling any tools or springs, prioritize safety. Wear appropriate personal protective equipment, including gloves and safety glasses, to prevent injuries during the mounting process.

Assess Mounting Points

Identify the mounting points for the constant force springs. Consider the application’s requirements and ensure that the chosen mounting locations can withstand the forces exerted by the springs. It’s crucial to distribute the load evenly to prevent uneven wear and premature failure.

Prepare the Springs

Examine the constant force springs for any defects or damage. Ensure that they are suitable for the intended application. If the springs are coiled, gently unwind them, taking care not to introduce kinks or twists.

Positioning and Alignment

Carefully position the springs at the designated mounting points. Ensure proper alignment to avoid unnecessary stress or friction during operation. If multiple springs are used, maintain equal spacing and alignment for uniform force distribution.

Secure Mounting Points

Using the appropriate tools, secure the constant force springs to the mounting points. Depending on the application, this may involve screwing, bolting, or clamping the springs in place. Follow the manufacturer’s guidelines for recommended fastening methods.

Test and Adjust

After mounting, conduct a thorough test of the system. Check for smooth and consistent operation. If adjustments are necessary, carefully release the tension and make any required changes to the mounting configuration.

Final Inspection

Conduct a final inspection of the mounted constant force springs. Ensure that there are no visible defects, and confirm that the springs are functioning as intended. Address any issues promptly to prevent complications during regular operations.


During the installation process, we must avoid applying excessive external force to the constant force spring to avoid damaging the spring or affecting its elastic performance.

After the installation is completed, we must regularly inspect and maintain the constant force spring to ensure that it is in good working condition.

If any abnormality is found in the constant force spring during use, such as weakened or broken elastic force, it should be replaced in time to ensure the normal operation of the equipment or machinery.


Mounting constant force springs with precision is a critical step in maximizing their performance and longevity. By following this comprehensive guide, you can ensure that your constant force springs are securely and accurately installed, contributing to the success of your application.
