1" (1.0) Inch Outer Diameter Standard Extension Springs
Definition of 1" Outer Diameter Extension Springs:
A 1" (one inch) outer diameter extension spring has an outer diameter of 1.0 inches. This is a heavy-duty spring size commonly used in powerful mechanical systems where maximum pull strength and longevity are crucial. These springs are ideal for industrial machinery, garage systems, large equipment, and rugged applications that require reliable tension performance.
At The Spring Store by Acxess Spring, we offer a wide range of 1" OD extension springs in different wire sizes, hook styles, body lengths, and load capacities — all ready to meet your project requirements.
How To Measure Your 1" Inner Diameter Stock Extension Spring
Your 1" (one inch) extension spring’s outer diameter is critical to the spring’s strength, tension capabilities, and durability under load. A 1" OD extension spring is designed to deliver consistent performance in environments that require high mechanical strength, long service life, and dependable pull force.
The 1.0" OD extension springs in our catalog are available in multiple configurations, such as different wire diameters, coil lengths, hook types, and body dimensions — allowing for precise tuning of the spring’s characteristics to match your needs.
All of our 1" OD extension springs are manufactured using premium 302 stainless steel (ASTM A 313) or music wire (ASTM A 228), ensuring excellent corrosion resistance, resilience, and fatigue life.
