Extension Springs

Gardner Spring manufactures and stocks high-quality Extension Springs engineered for consistent tension, dimensional accuracy, and long-term performance. We provide in-stock solutions backed by over 115 years of engineering expertise and fast fulfillment.

What are Extension Springs?

Extension Springs, also known as Tension Springs, are designed to absorb and store energy when stretched. They operate under tension, returning to their original length when the applied force is removed. These springs are commonly used to maintain pulling force, control motion, and support mechanical function in industrial and commercial assemblies.

Gardner Spring offers Extension Springs for a wide range of applications and operating conditions, including small Extension Springs for compact assemblies and heavy duty Extension Springs for high-load environments. Our inventory includes multiple material options such as stainless steel Extension Springs, music wire Extension Springs, and zinc plated Extension Springs to support both general-purpose and demanding industrial applications.
