9 best mechanical extension springs
Mechanical extension springs are a type of helical spring commonly used in various industrial and mechanical applications.They belong to the category of springs used for providing linear force or tension when stretched or extended. Here's what you need to know about mechanical extension springs in the context of Springs and Industrial Scientific applications:
Design and Function:
Helical Shape: Mechanical extension springs are typically made from round wire wound in a helical (spiral) shape. This design allows them to store and release energy when subjected to a force.
Extension and Compression: While most springs, like compression springs, exert a force when compressed, extension springs exert force when stretched or extended. They work on the principle that the force needed to extend the spring is directly proportional to the amount of extension.
Load-Bearing: Mechanical extension springs are designed to bear loads in tension. When they are extended, they resist the pulling force and return to their original length when the force is removed.
Applications: These springs find use in a wide range of applications, including automotive, aerospace, industrial machinery, and consumer products. For example, they are used in garage door systems, trampolines, farm machinery, and various types of mechanical devices.
Key Characteristics:
Materials: Mechanical extension springs can be made from various materials, including high-carbon steel, stainless steel, and non-ferrous alloys. The choice of material depends on factors such as environmental conditions, load requirements, and corrosion resistance.
Ends: The ends of extension springs are designed with different configurations, such as closed and ground ends, open ends, and looped ends, to facilitate attachment to other components.
Wire Diameter: The thickness of the wire used to make the spring influences its strength and load-bearing capacity.
Length and Diameter: The physical dimensions of the spring, including its length and outer diameter, are important factors in its design and application.
Load and Extension: Mechanical extension springs are designed with specific load and extension characteristics, which should be matched to the requirements of the application.
Installation and Maintenance:
Proper Installation: Correct installation is crucial to ensure that extension springs function as intended. This includes securely attaching the ends to the components they will operate on.
Maintenance: Periodic inspection and maintenance may be required to ensure the springs are in good working condition, especially in applications subject to heavy wear and environmental factors.
Mechanical extension springs are versatile components used in many industries due to their ability to provide reliable tension and linear force. Proper selection, installation, and maintenance are essential for their effective use in various applications.

User questions & answers
Question: | is the 10" length just the spring coil, or does it include the loop ends |
Answer: | I don't think so. I used them to connect 1 1/4" drain from the bathroom sink to 1 1/2" house drain. It worked well for this, can connect pipes of the diameter. You could cut the threads off and then use the coupling. |
