An Extension Helical Spring is a mechanical spring designed to operate under tensile or pulling forces. Also known as an extension spring, it stretches when a load is applied and generates a restoring force that pulls the connected components back toward their original position.
Extension helical springs are manufactured from spring wire wound into a helical coil. They commonly feature hooks, loops, or other attachment points at the ends, making them suitable for connecting components in mechanical assemblies.

Applications of Extension Helical Spring
An Extension Helical Spring is commonly used in machinery, automotive components, agricultural equipment, tools, laboratory equipment, mechanical assemblies, and industrial systems. It is ideal for applications that require controlled pulling force and return movement.
How Extension Helical Springs Work
When an external pulling force is applied, the spring extends and stores mechanical energy. When the force is removed, the spring contracts and produces a restoring force. Its performance depends on factors such as wire diameter, coil diameter, free length, number of coils, spring material, and working load.
Choosing the Right Extension Helical Spring
When selecting an Extension Helical Spring, consider the required load, free length, maximum working length, wire diameter, coil diameter, attachment style, material, and operating conditions. Choosing the appropriate specifications helps provide dependable performance and longer service life.
Extension helical springs are an effective solution for mechanical systems requiring pulling force, controlled movement, return action, and energy storage. They are available in different sizes and configurations for a wide range of engineering and industrial applications.
