Extension springs are springs which absorb and store energy by offering resistance to a pulling force. Various types of ends are used to attach the extension spring to the source of the force. Extension springs are usually straight, tapered, and conical. Extension Springs are tightly wound coils designed to absorb and store energy by resisting a pulling force. Commonly used in automotive interiors, garage doors, and industrial machinery, they return to their original shape when the force is released. We are reliable manufacturers, suppliers, exporters, dealers, traders, Wholesalerrs, and providers of extension springs in Mumbai, Navi Mumbai, Thane, and across India. Our high-quality extension springs are known for durability, precision tension control, and customizable end hooks to suit a wide range of applications.

D (wire diameter): | This parameter describes the diameter of wire used as material for spring. |
De (External Diameter): | External diameter at large end of the spring. Tolerance for this parameter is (+ -)2%(indicative). |
Ds (Internal Diameter): | Internal diameter at small end of the spring. Tolerance for this parameter is (+ -)2%(indicative) |
B.L (Body length): | Body length of Extension springs is measured in its uncompressed state Tolerance for this parameter is (+ -)2%(indicative). |
F.L (Free length) : | Free length means distance between two hooks .(Inside Hooks) |
R (spring rate): | This parameter determines spring’s resistance, while it is working. It is measured in 1 DaN/mm = 10 N/mm. Tolerance for this parameter is (+ -)15%(indicative). |
