Industrial Extension Springs: High-Tension Helical Solutions
Extension Springs, also known as tension springs, are designed to absorb and store energy by offering resistance to a pulling force. These springs are attached to other components at both ends, and when these components move apart, the spring attempts to bring them back together. At [Your Brand Name], we manufacture precision extension springs that provide consistent force and exceptional durability.
1. Advanced End Configurations for Secure Attachment
The reliability of an extension spring often depends on its ends. We offer a diverse selection of hooks and loops to ensure a secure fit for your assembly:
- Machine Hooks/Loops: The most standard and cost-effective end style formed from the spring body.
- Extended Hooks: Used when the attachment point is further away from the spring body.
- Swivel Hooks: Designed to rotate freely, reducing stress and preventing torsion during operation.
- Side Loops: Offset hooks used for specific clearance requirements.
2. Quality Materials & Technical Precision
We utilize CNC-controlled coiling technology to ensure every loop is perfectly aligned and the initial tension is uniform across every batch. Our material options include:
- High-Carbon Steels: Excellent for high-cycle applications in dry environments.
- Stainless Steel (302/316): Essential for marine, medical, and food-grade hardware.
- Corrosion-Resistant Coatings: We provide Zinc, Nickel, and specialized powder coatings to withstand harsh industrial conditions.

Frequently Asked Questions (FAQ)
Q: What is Initial Tension in extension springs?
A: Initial tension is the internal force that holds the coils tightly together. This force must be overcome before the spring starts to extend. We can customize this value based on your specific assembly needs.
Q: How do I measure the length of an extension spring?
A: Standard measurements are taken from the “inside” of one hook to the “inside” of the other, known as the “Length Over Loops.”
Q: Can hooks be oriented at specific angles?
A: Yes. We can manufacture hooks at 0°, 90°, 180°, or any custom degree of relative orientation to fit your mounting points.
Q: What is the most common failure point for these springs?
A: Most failures occur at the base of the hook. We offer “Stress-Relieved” hooks and reinforced designs to maximize the life of the spring.
